A couple walked into a cheap restaurant

A couple walked into a cheap looking restaurant.

As they were about to sit down they noticed there were crumbs on the seat, after cleaning up the seat and wiping down the table they sat down.

A waitress came over asking them what they wanted, “I’ll just take a coffee” said the man, “me too” said the lady “and make sure the cup is clean.”

The waitress returned with their drinks “OK” she said placing down their cups “now, which one of you wanted the clean cup”.
