Why Do Americans Hate $2 Bills (Excluding Collectors)

I work for a British cruise line and sometimes have to escort cruise passengers from Dover to Heathrow airport. A couple of years ago an American passenger tipped me with a $2 bill (1995 series). I'm looking forward to spending it next time I visit the States!

Here in the UK the £2 coin (first issued as a circulating coin in 1997) is quite common, but I've noticed that, when changing a £5 note for something costing £1 or less, it's more common to receive four £1 coins (or two £1 coins and one £2 coin) in change than to get two £2 coins. It may be that cashiers think people prefer to get £1 coins in change as more vending machines accept them.

My wife's grandfather used to work in a shipyard back in the 50's and when he got paid they would give them their pay in the fewest notes, so he got red seal $2's every week. People now think they're rare for some reason.
The strip club across the river uses them to get more in tips for the girls. All the drinks are priced in even dollar amounts so no 1's are needed. All the drunks have is 2's for the, um, "dancers."
Here in CT it's hard to find 2's in banks for some reason though.
