like most officey places everybody has to hold up a key card to a thingie to get in/out. some people choose not to take it out of their pocket and instead hip thrust or touch their butts to the card reader
I once saw somebody do a 360 next to the door until it beeped
basically I work with the best people
A lot of people here keep them in their wallets, and turn coming back from group lunch into a contest of who can hit the reader with their wallet from furthest away.
