Fair for Exclusive or Private clubs to be prejudiced among babysitters?

My husband and I are members of a Private Club in Hong Kong. This morning, I had my son taken to the doctor for his 12th month immunization. Because he got very upset with the needles, I thought it would be nice to cheer him up by buying him a new toy for being brave anyway (he had 2 shots today!), so my (full time-stay-at-home) babysitter, my son and I ended up going up to the club so he could play in the kiddie's room while i lookedfor his toy.
