Is my account hacked or is door dash takin money?

So my boyfriend checked his transactions at work we been ording food from door dash for a while now but I always tell him how much the food comes up to (he uses his card on there ) like if my meal comes up to like 12$ or more something always takes wayyyy more money off his card with out us knowing it dosnet let us know on the app but it showed up in his transactions at work so I'm confused who could be takin this money off has anyone had this problem before?
