I don't know what kind of friends you have, but mine take offense to being offered something they didn't ask for, like they are beggars or are owed something.

He stayed with me for a week last year. We had a big bbq. I stuffed him full of akaushi beef. I didn't ask for a dime, nor would I ever.

I guess you maintain friendships with an excel sheet handy? good for you I guess
