Okay but that glass isn’t free - it’s built into the cost somewhere. Maybe it’s a lower quality unit or maybe it’s just a better deal, I dunno.
As far as 4 screws go, yeah, but they’re screws, not bolts, so do you really want to be removing them and screwing them back on, every time you want to clean the thing?
Also (and they may all be built differently, who knows) I feel like when I put mine together, I think I realized that removing the sneeze guard meant disassembling the sneeze guard? I dunno, but I quickly decided there was no reason to be dealing with that glass.
