> They do when they are at work.

what, they don't have their company-provided mug with the company logo on it? Though to be fair at work, most employee have been given a mug, there's a stack of freely usable mugs next to the coffee machine and there's a dishwasher there too so you don't have to wash them by hand, but there are still people using the paper cups.

I'm sure a lot of workplaces have a kitchen with an assortment of random mugs. Maybe this is true at a construction site, but nowhere I've ever worked lacked non-paper cups.

Nope! The number of jokes I get at the office coffee machine (well the nespresso next to it) with my shot glass, you wouldn't believe. btw anyone tried the seaweed sphere capsules? :-)
