S2 Ep 7. Ratz nibble on stealing towels, wyr, tipping

Kate and Thibaud nibble on hotel towels, how sanitary they actually are, and how we absolutely definitely no longer need to take them home. For would you rather it's between a stranger wiping your behind every time you go number two OR use a towel to wipe your behind each time you go number 2 AND always tip zero and everyone at the restaurant would know OR always tip 30% and no one would know.
