Unless, that is, you're dining out. I do drink occasional alcoholic beverages but the last time I was out to dinner with my family and the waitress asked if we'd be interested in drinks and I declined while asking for an additional water, she gave me a not-quite-concealed eye roll. The message was loud and clear: she wasn't going to make much off my table. I can hardly blame her. Tips are how waitstaff make money, and if you order drinks the check is going to be a lot bigger.

This is also why some people say weird things like you're "cheap" if you don't order drinks (especially if you are paying).
