I have gone to the same pharmacy for the few years I was living in IL, there was always one pharmacy tech who was very rude to me. She would purposely ignore me when I walked up to the counter, she once spent 15 minutes , i kid u not, 15 minutes with a lady in front of me dropping off a script.
She priced it, and explained it to her and when it was my turn I asked her how much it was so I can plan accordingly, she told me she couldn't find out till she billed it, I asked her why couldn't she just run it thru, it takes about a minute, she said they were busy, I said maybe you shouldn't have had a full off topic conversation with the previous lady. I said "whatever" she helped the next person and then another person after the guy after me. She also spent time with the 3rd customer.
I noticed a pattern, she was treating whites like *** and the hispanics like kings and queens. I called the 800 walgreens number and they dealt with her, she was NEVER rude to me again, yell and scream and you will be heard.
