You guys are probably right I am just being paranoid, but still I can't be the only person who is uncomfortable seeing a tip line on a credit card recept at a "call out your number when your order is ready" type of place. Tip jars are one thing, they are more like a "don't want your change" jar and can be easily ignored, but it is just tacky to have a tip line, then you always feel like a cheap jerk when you cross it out.
