My guess is this is not Red Hen situation where management was behind or aware of the vile discrimination.
Adorama, like the other large NYC camera outlet is owned and managed by Orthodox Jews who in general are conservative. They do have a fairly “diverse” front of the house staff.
Adorama would be crazy to take any political stand. Not right wing (most NYC creative types. very liberal)or anti Trump.
sounds like a renegade sales person who needs to be fired,but would probably claim discrimination if he was.
 Is that 47th St. Photo? I have not been in NYC in a long time.
