So, I have to pay my MUA her balance due in cash on the day of the wedding, which is perfectly understandable. However I was thinking instead of taking a boatload of cash out of the bank for vendor tips in addition to MUA fee, I would just write checks and put them in an envelope with a nice note? Is this okay? Otherwise I am going to have to carry around like $2k worth of cash in envelopes for everyone's tips and I'd rather not. And I have overdraft protection so there's no chance my checks will bounce.
