Holiday Gifting

Its that time of the year again,when you have to loosen the purse strings and gift the folk who have helped you all year long . I am referring to doormen, supers and porters. Incidentally we just called our super to inform him that we would be mailing checks for him to distribute. Are you as tenants also expected to tip around the holidays?Do you confine yourselves to building personnel or do you include your regular dry cleaners, the postmen who deliver your mail to your building, your hair stylist and others to the list?
