How are tips from customers handled?

Cash. Gifts. Gift cards. Check. Paypal. Cash me. I have received a gift card for Target, cash from my regular clients, many referrals on nextdoor, and cash in the mail! That was a wonderful surprise :) Whatever you choose will be greatly appreciated. Nothing different than tipping your hair cutter or cab driver or Uber driver ;)

Cash is best. Gifts, business referrals, and great reviews are also appreciated. Otherwise, you could tell the sitter you'd like to tip and ask if he/she would give you their email connected to pay pal.
