My co-worker just went to grab lunch. I gave her my debit card, but when she came back she told me that she just decided to pay for it!

I would say this happens at least once a week. Co-workers say they're going to get lunch, ask if anyone else wants anything, and then say "I'm buying."

It's so nice! They buy coffee at least once a week for me, too.

Needless to say, I try my best to return the favor whenever I step out for lunch or a coffee!
