I think if you ask the Valets - Surely They know! It will be Tip, and Tip some more . . . . You keep Tipping till it hurts. Cuzz if'a you don't, I'ma gonna fix'a you cah ! Got it ?
Living in Vermont, I don't know; so I just goggled "Proper Tipping Etiquette" and got 99,000 responses. You've got your reading agenda for the Evening ! You'll be able to refine your search to Valets
You've got a pretty unique problem there. Did the Real Estate People possibly Fail to Disclose the Tipping Expense ?
In the annals of Real Estate, this may be a first! If you knows, then you must disclose! Please let us know what the Proper Etiquette Guides say AND What the other Condo Owners say is the "Usual and Customary Tip" AND What the Valets say they want AND What the Auto Repair People say it will cost to Fix your Car when you don't pay up !
Good Reading AND Good Luck !
