Not OP but my guess is that they're already using bad AI images for their kebab business, and OP wants them to use better AI for their images (so they may actually lose fewer customers because the AI imagery isn't so awful)

Why do you care what your kebab shop uses for their menus? These people are trying to run a business. If this can allow them to clearly communicate prices in a well designed pleasant way, it's great. Why must they slave away in design and technology or pay someone to do it for them? I think it's great

It would be an improvement, probably, because they are still using Dall.e 1 apparently.

Loose them on what?

loose? only if they don't cook it well
