Good....
I don't mean this as support, but the entire food and restaurant industry works based on migrant and undocumented workers. Hopefully more people realize this, because I can't imagine most of it is legal outside of missing documentation, and if that's why we have cheap food... honestly we need to see the real price of food especially when everyone is paid fairly, not turn a blind eye to migrant and undocumented workers.
Maybe more people will wake up to this.
Though also it's possible that the stores are just bare because they missed a delivery or something else. I've seen stores like that the day before a delivery because there was a rush on X or Y... One day I just wanted a bell pepper and my persian market that has some of the best and most consistent produce ever was just out of them. IT happens.
Also technically that's a Walmart... Maybe people count it as a grocery store, but there's a lot more at play in a walmart (And not somewhere I'd go for produce in the first place)
