It's just what Americans are used to. When my family's in America, we tip. When we're in Europe (especially if it's a small inn or something where the proprietor is also the server, where it's insulting) we generally follow the local rules. But here, servers expect a tip and have for a long time. It's built into their wage structure...I believe some actually receive less than minimum wage, and depend on tips to make a livable income.

Normally, in the States, I leave a 20% tip if the person has done a fairly good job. I've had some abysmal service and left some small tips accordingly, but I don't do it often. $1.32 would just be insulting to a waiter, and then you risk something happening to your food next time.

For the record, I hate McDonald's and haven't been to one in about 15 years. And that time it wasn't my idea.
