Deborah in MD

I am a monthly parker in a garage that parks and retrieves the car for you – it is policy. Daily I tip which ever attendant $1.00. Would a tip of $50 for the manager, $25 for the a.m. attendants (almost no interaction with them), $30 to the p.m. attendants, and $25 to the young lady who takes your ticket, finds the key, and passes it along be sufficient? Thanks so very much.
