With there being more and more girls working and less money to go around, personally I would be happy that I was free to work and have the extra work. I had countless calls that I had to say no to due to my son still living with me. He did go out Xmas eve for a few hours and I managed to squeeze 2 bookings in and the guys were really grateful, as they said no one was working.
God knows if I'll manage to get some time next year, but I wouldn't look a gift horse in the mouth if I could and knowing I would make a fair bit of money, I would not ask for extra.
