For a couple of years now I have been working at a shop in a very, very impoverished and rough part of my city that is predominately occupied by low income minorities. I hope this doesn’t come off condescending but it took me a while to realize that a not insignificant number of our customers struggled to read the menu and price, info ect about products we had. I feel bad even for being a bit frustrated in the past by this, and we do our best to accommodate everyone and make them feel welcomed now I like to think anyway. But this is certainly a widespread issue that is rarely discussed or understood especially by those who reside only in wealthier areas or what not.
