so when i get big bills i always like to quickly run my fingers over them and in the case of hundreds i hold them up to light really fast... and when i get that inevitable "joke" about the money being real/fake/etc, i always pretend i didnt hear it and continue on with my work. i'm not about to stop my checking of your dangass money bc u think ur funny. ill just count out your change to you, hand u ur receipt, and send u on ur way. stew in ur shame, old man. stew in it.
