I do think this one is sweet, actually, and not just because it deals with strawberries, which are always a good thing.

The sweet part is the sign-maker’s concern for your well-being. You don’t want to get stuck in this shop trying strawberry sundaes forever, see. You just want to do it for a limited time.

As for the other… I can’t decide if it might have been improved by an apostrophe in “Sundaes,” and the fact that I’m even pondering that gives me hives.

ETA: Thanks to Chris H. for sending this in!
