person A: When I go to a bar with my girlfriends and a guy offers to buy me a drink_comma_ I always decline because I have a boyfriend. I wouldn't want to lead anyone on and have them spend money on me!
person B: Girl_comma_ take that drink and don't be ashamed. At least you wouldn't have to pay for the drink!
person A: True lol but I feel sooo guilty and I don't want anyone to have expectations that I am definitely not going to meet
person B: That's when you say politely_comma_ I'll take the drink but not your number. Nothing to feel guilty about since you would be using your manners.
