My Work Gave Me A"christmas Gift" But Took The Price From My Paycheck?

I work at a gas station, so fancy.

But my work place gave me a $50 for said gas station, and a nice jacket. I was happy and thought "awesome, free gas money"

I looked at my check today, and it shows there was $50 deducted for "gift"

So they took $50 from my paycheck, and used it to give me a $50 gift card. Essentially forcing me to use my money there. Is this even allowed considering I never agreed for them to use my money for the gift?

Edit: I found the issue.

I overlooked it showing +50 in my income so they added $50 then out that on the gift card.
