Hold on... we are arguing about scale that's off by 1 or 2 pounds? Isn't that like a given? I've seen 1-2 pound difference between my outbound flight and return flight, which lead me to conclude dirty clothes generally weigh less according to airlines... I am more curious as to how people around you reacted when you opened your suitcase full of panties and women's clothing, and you had to decide which pair of the string panties you had to pull out!
I'd be like just charge me the $100...
