The water cooler (of doom) only accepts official cups of DUPA genetics.
Indeed. You found the plain mug? ?
There is a mug in the left cupboard, near the fridge.
Cool... Now, you could make it look like the official cup. Find some reference what the official cup looks like. ?
Look at the note on the fridge.
So, the official cup has the DUPA genetics red logo on it.
Take a red pen from the table. Use it on the mug to get it to look like an official cup. Artistic!
