I know we all have this paranoia at times, but nothing will happen to you. The city does not have the money or the resources to crack open the establishments phone logs, find details on their clients, review security camera footage, build a case, get an arrest warrant, to then bring you to court…for what? To put you in jail? To make you pay a fine? Unless you’re a celebrity or person in a position of power and influence, I think you’re ok.
