Would it be a dick move to report a bodega to 311 for not displaying prices?

I’m starting to get really annoyed with stores not marking prices. I ask the price and the clerks seem annoyed that I even bother, like I’m petty or miserly. We’ll today, I didn’t ask. I didn’t to be judged. But when I got the bill, all I could think is: “$13.50 for a plain grilled cheese and an ice cream sandwich? The nicest place around me charges much less”.

I just want to be an asshole and report places left and right now. Prices should be transparent
