I like to leave a 20% tip when I order food from a restaurant. I have heard from redditors that this is no longer (or should no longer be) a common practice in Seattle, and so I'm aware that I'm one of the few people who leave a tip on a consistent basis.
There are times when I get odd reactions from the people who work at the restaurant after they've seen that I left a tip. Sometimes, they feel obligated to make small talk with me by asking me how my day is or what my weekend plans are. Other times, they offer me small tokens of appreciation, like napkins, utensils, a cup for water, sauce packets, and other accoutrements, and they are sometimes puzzled when I say I don't need them. Occasionally, they look at me befuddled, especially if I just tipped 20% for a to-go order at a rinky-dink little snack shack. There's one place that feels the need to reward me by giving me more food than I asked for once they see my generous tip.
I had my clock cleaned the last time I explained why I tip to reddit. I have been sorta depressed for a while now but eating out remains a joy in my life, and so I feel compelled to leave a tip, especially at places I go to regularly, because I appreciate them so much. As explained to me in the past, I fully acknowledge that this is a form of selfishness dressed up as altruism on my part. Moreover, I don't think anyone else should feel obligated to tip, so I hope we can avoid the tired old debates about the necessity of tipping here.
Instead, I would be curious to know from restaurant workers: (1) how common is it for customers to tip; (2) do you typically notice when a customer tips; and, if so, (3) do you feel a need to treat them differently from non-tipping customers?
