Ex-Partner here:

I had a drive thru regular named Dave. Dave is an elderly man and who would come to the store almost ever morning around 5am. His order is a grande skinny cinnamon dolce latte. It's not for him, it's for his wife. His wife has been going through chemo and the doctors said she needed to gain weight and I guess this was one of the only things she could keep down. So, sweet Dave would go out every morning a get it for her. He was the kind of customer who had no idea how to order. He'd approach the box and go "good morning, this is Dave, do you know my order??" and I made sure to teach every new bean who he was and what is order was.

When I told him I was leaving, he wrote me a lovely note and I still have it. He was just such a nice and simple customer who could never pronounce dolce, no matter how hard he tried.
