The last few days I've been eating lunch at Yoshinoya, the gyu-don (beef bowl) fast-food place on Drumm St (bet Sacramento & California) in the SF financial district. There are usually two counter people taking orders. The one on the left is a trip. She's an older Asian (Chinese?) woman, and she seems so INTO taking your order as quickly as possible and getting you out of there. It's like she's out of breath because she just can't stand for you to be wasting her time making up your mind. She does her best to upsell everyone on the combo set (includes salad and drink), but I'm not sure whether she does it for the extra revenue or because it's quicker that way (you won't be wasting her time thinking about side dishes). Once I fumbled for my change and I think she was about to bite my head off. Though her behavior could be taken as rude, I think she is just really dedicated to speed. I'm not usually in a rush, but I can't help admire her work.
