Have seen enough before and since COVID to say that 15-18 months is about the expected lifetime of the majority of these types of small businesses. I've got pretty good at predicting those that will not survive. You look at them and ask yourself what are they offering that will stand out in a saturated market, where will the customers come from...foot or motor vehicle, where is the parking, adequate signage, no website/Facebook, not on Google Maps or if they are, without the correct or any GMB categories.
