Cruel? There are a set of pretty arbitrary customs about where you tip and where you don't tip. You would be considered a weirdo if you tipped at the grocery store. In the US, you have to tip at sit-down restaurants. Traditionally, in the US, people rarely tipped when they had to go to the counter to order and pick up food. That's just the custom, though it seems to be rapidly changing, so that basically any food or drink service now involves tipping.
