Actually, you need to talk to someone in HR and have that person talk with the admin and explain that extortion is both illegal and against company policy. Guilting someone into contributing to a party and gift they don't support is white collar extortion. Many companies don't mind when this is completely voluntary, but have rules against targeted philanthropy.
Love this!
I also really dislike the collection of money for birthdays, the routing around of the group birthday card for signatures. This stuff usually starts out sincere, but after the 3rd or 4th birthday of the month it gets annoying and some people also start vying to out do each other on the preparations. Please let me get back to work, and if I like you, I will take you to lunch on your birthday or send you a separate card anyway.
