Last night on my way to class, I stopped at the Starbucks on my way to campus because 1. They're on the way there and 2. They're open later than my store. I used my market and I put a few dollars in their tip jar which was empty. The way the girl at DT said thank you sounded like no one had tipped all day. I'm just curious if a lot of other people tip when they're at a different store or when they visit their store on their days off.
