Publix Super Markets review: terrible customer service

I have been a loyal Publix customer since I was a little girl, 17 plus years. It has always been my families grocery store due to the excellent customer service . It truly makes us feel so comfortable and we trust the Publix brand. Until this past Friday July 11, 2014 . I am never one to complain but I just cannot turn a blind eye to this terrible incident. I went in to do my weekly grocery shopping at my regular Publix store at, 4402 Curry Ford Road Orlando, FL 32812 location, and noticed there was a sale on a particular item that I purchase quite a bit for my family (CapriSuns). The sale was for $1.79 and there was an instore coupon for $1.00 off each. When I went to grab this item it said it was limited to 2 boxes per customer. Which I did pick up 2 boxes and so did my partner. When I went to the register to pay for my groceries, the store manager Manuel Aybar approached me and told me that as of that moment we coud only purchase one per day which is not what the sign said. I proceeded in telling him the sign clearly said 2 boxes per customer and offered to show him. He said he didn't care what the sign said (not a very pleasent way to be speaking to your customers); that he was only allowing me to purchase one unless I walked out and back into the store. Then I could go get more or make the purchase in separate transactions and then he walked away. I proceeded in following his instructions to make my purchases on separate transactions and then he came out of his office infuriated because I was still standing there making my purchases. Then he proceeded in telling me that it was only if I walked out of the store and walked back in humiliating me infront of my family and the rest of the publix customers that evening. I went ahead and walked out and back into the store like he told me and then he yelled at me and said, "Make sure you never come back to this store I will be notifying all my employes and managers". When I asked why he said, " because I can". As you can see from this situation that is NO WAY to speak to anyone much less a loyal customer. My only crime was to go buy my groceries that night while he was working . I understand that everyone is entitled to a bad day but that is no way to tread your customers. All I wanted to do is purchase my weekly groceries, however I was treated like an animal. Your brand is so well known for their EXCELLENT customer service do not let one rotten apple spoil the rest. This is not how you want your brand to be represented. This is uncalled for and not acceptable behavior specially from a so called manager that is supposed to be seating a good example to their employes. I am embarrassed and very disturbed by this situation. I expect this inhuman behavior to be rectified.
