It’s impossible to get any satisfaction from playing for free to a noisy audience and my immediate (personal) solution would be to pack up and play somewhere else. If money was involved, my fee would increase to the point where the benefit exceeded the annoyance caused by the audience.

One technique I often used when running a sound system with noisy audiences was not to try and compete with them but turn the volume down until the act was barely audible above the noise which tended to quieten them down. I admit there is little you can do with espresso machines, fruit/pinball machines etc.
