<human>: So I (F24) work part-time as a waitress (trying to pay off student loans) and I have a huge crush on guy who tends to come in for breakfast or lunch a couple of times a week on the days I'm working.

He's handsome, super sweet, and I'm pretty sure he's single but I'm not 100% sure. If I had to guess, I'd say he's 25-27. I've gotten to know him a little bit since we sometimes talk if I'm not too busy. He said he moved here a few months ago. I'd love to ask him out but I have no idea how and plus, I get really nervous around him. 

Whenever he comes in, my manager always makes sure I get him since she knows I have a big crush on him.

His bill is usually between $8 and $9 but he ALWAYS pays with a $20 and tells me to keep the change. Do you think that might be a sign he likes me? 

My manager said she's seen him drive a really expensive sports car a couple of times, so the large tip might not mean anything. But she said she catches him looking at me quite a bit and said he never comes in when I'm not working.

Considering I'm kind of a shy person, what's the best way to ask him out without being extremely embarrassed or nervous? My hands are sweating just thinking about it!

<bot>: What's the best way for a shy girl to ask a guy out who's really handsome and outgoing? I'm nervous a bit intimidated.
