I'm an intern in a team of ~15, half are managers other half are interns.
To be nice, I anonymously left a box full of 50 coffee capsule for everyone to use near the coffee machine. The morning after, I came to see there was only 3 left.
later in the week I saw that one of the managers had many capsules of the same type on his desk.
Can't prove anything and not willing to confront him anyway.
But wow. This guy probably gets paid 5 times what I get as an intern
