Extremely Rude!
I came here to pick up a small parcel, and the manager himself (his name tag says Store Manager: SUN) made me wait AN HOUR, and during the whole time my small parcel was right beside him on the counter! No smile, no greeting, no explanation, and of course no apology! The only two words he said during the whole hour were “Wait” and “ID”. If you really want to see how rude a person can be, go to this store.
