I feel very blessed to work for a company that has multiple forms of complimentary food offered. There is usually a candy bowl or Costco sized pretzel bin at the receptionist's desk, coffee K-cups in the kitchen, and an assortment of ice cream in the freezer. The company buys staff (maybe 60ish employees) lunch on a Friday once every other month.
I usually bring my lunch to work, and I have a mini-coffee maker under my desk (it only makes 5 cups). I will have company coffee on days when I don't feel like brewing my own, and I will have ice cream maybe twice a week. I engage in pretzels and candy maybe twice a day, nothing absurd though, a few here and there.
There is a coffee collection next to the Keurig, and and ice cream collection near the freezer. I toss in $5 once in a while.
I feel guilty though. I don't really have any spare money to toss into the collection than I'm already contributing (kids, wife, life, etc.). And on occasion I bring in candy to refill the candy bowl so I can contribute that way too.
Should I be self-conscious about this? I feel I contribute enough (money and donations), and I rely on my own coffee and food most of the time. I say "thank you" to management and the people involved in providing the free goodies, but I still feel like I'm getting away with robbery because I feel like what I take/eat is worth more than the amount I'm putting in.
