Attitude of check out clerk at counter 7/14 AM

I frequent this shop for both charity and good buys for many years. On this particular date, today, I met the most unprofessional, condescending check out clerk at the counter that I ever met while shopping at Goodwill for decades. She was hostile and condescending. ("what does that sign say?" She lectured, implying I could not read.) By the way, I am an elderly Asian with a Ph.D from an elite university and retired professor at the University of Michigan. I also have produced major publications. I noticed she is uniformly hostile to Asians. This is destructive attitude for this particular store. Store manager should know that this area is populated by wealthy Asians. I would urge Asians not to shop at this store and there is a nearby GW at Diamond Bar City. Black racism is just as obnoxious.
