Should I visit my favorite lunch spot less after they keep comping me?

Every Friday at work for about a year I stop at the same place for lunch and order the same thing. Normally I pack a lunch. Just once a week I like to treat myself for lunch. The past couple times they haven’t charged me which I think is really nice of them. I tell them I don’t mind paying. So I leave some money in the tip jar on the front counter. I feel really bad because they’re really nice people that work there.
