After my rant on tip jars, I just wanted to mention one place I frequent that has tip jars that I don't mind at all. The workers at a local ice cream place - the kind that pounds the different toppings into the ice cream - promise to sing for you if you put a tip in the jar. Sometimes you might want to put another tip in to get them to stop , but I find their creativity and desire to at least do something for a tip amusing and well worth a little extra.
