The following are actual stories told by travel agents (and you wonder why
US citizens generally score less than the rest of the world on
geography)...

• I had someone who wanted to stay at the Bob Newhart Inn in Connecticut.
  When I explained that the inn was fictional, the customer became very irate
  and insisted "I know it is real, I see people check in every week!"
  Also, I really did have someone ask for an aisle seat so that their hair
  wouldn't get messed up by being near the window.
• A client called in inquiring about a package to Hawaii. After going over
  all the cost info, she asked, "would it be cheaper to fly to California and
  then take the train to Hawaii?"
• I got a call from a woman who wanted to go to Capetown. I started to
  explain the length of the flight and the passport information when she
  interrupted me with "I'm not trying to make you look stupid, but Capetown
  is in Massachusetts." Without trying to make her look like the stupid one,
  I calmly explained, "Capecod is in Massachusetts, Capetown is in Africa."
  her response....click.
• A secretary called in looking for hotel in Los Angeles. She gave me various
  names off a list, none of which I could find. I finally had her fax me the
  list. To my surprise, it was a list of hotels in New Orleans, Louisiana.
  She thought the LA stood for Los Angeles, and that New Orleans was a suburb
  of L.A. Worst of all, when I called her back, she was not even embarrassed.
• A man called, furious about a Florida package we did. I asked what was
  wrong with the vacation in Orlando. He said he was expecting an ocean-view
  room. I tried to explain that is not possible, since Orlando is in the
  middle of the state. He replied, "Don't lie to me. I looked on the map and
  Florida is a very thin state."
• I got a call from a man who asked, "is it possible to see England from
  Canada?" I said, "No." He said "but they look so close on the map."
• Another man called and asked if he could rent a car in Dallas. When I
  pulled up the reservation, I noticed he had a 1-hour layover in Dallas.
  When I asked him why he wanted to rent a car, he said, "I heard Dallas was
  a big airport, and I need a car to drive between the gates to save time."
• A nice lady just called. She needed to know how it was possible that her
  flight from Detroit left at 8:20am and got into Chicago at 8:33am.I tried
  to explain that Michigan was an hour ahead of Illinois, but she could not
  understand the concept of time zones. Finally I told her the plane went
  very fast, and she bought that!
• A woman called and asked, "Do airlines put your physical description on
  your bag so they know who's luggage belongs to who?" I said, "No, why do
  you ask?" She replied, "Well, when I checked in with the airline, they put
  a tag on my luggage that said FAT, and I'm overweight, is there any
  connection?" After putting her on hold for a minute while I "looked into
  it" ( I was actually laughing) I came back and explained the city code for
  Fresno is FAT, and that the airline was just putting a destination tag on
  her luggage.
• I just got off the phone with a man who asked, "How do I know which plane
  to get on?" I asked him what exactly he meant, which he replied, "I was
  told my flight number is 823, but none of these darn planes have numbers on
  them."
• A woman called and said, " I need to fly to Pepsi-cola on one of those
  computer planes." I asked if she meant to fly to Pensacola on a commuter
  plane. She said, "Yea, whatever."
• A business man called and had a question about the documents he needed in
  order to fly to China. After a lengthy discussion about passports, I
  reminded him he needed a visa. "Oh no I don't, I've been to China many
  times and never had to have one of those." I double checked, and sure
  enough, his stay required a visa. When I told him this he said, "Look, I've
  been to China 4 times and every time they have accepted my American
  Express."
• A woman called to make reservations, "I want to go from Chicago to
  Hippopotamus, New York" The agent was at a loss for words. Finally, the
  agent: "Are you sure that's the name of the town?" "Yes, what flights do
  you have?" replied the customer. After some searching, the agent came back
  with, "I'm sorry, ma'am, I've looked up every airport code in the country
  and can't find a Hippopotamus anywhere." The customer retorted, "Oh don't
  be silly. Everyone knows where it is. Check your map!" The agent scoured a
  map of the state of New York and finally offered, "You don't mean Buffalo,
  do you?" "That's it! I knew it was a big animal!"
