I went to get a cup of tea at a coffee/tea place at the mall, and a woman who works at one of the other food places (the hot dog place - but not the kind with the funny hats) insisted on buying me a cup of tea. This woman was a complete stranger (except for the free sample of hot dog she'd given me earlier) and someone who likely works hard for a modest income. But she wanted to buy my tea for me. I kept refusing, and offered to buy her tea for her, but she insisted. And then, when it came time to pay, the cashier comped both cups of tea (that is, she didn't charge us at all). So I put my two dollars in the tip jar, and promised that next time I was at the mall I'd get a hot dog.
And then I went outside and cried, because really, when was the last time a stranger offered to buy you a cup of tea out of the blue?
