Bad attitude of staff especially cashiers

I shop at Shoprite Parow, Station Road branch every other day to buy random items, as it's conveniently situated on my way home from work.I have been doing so for the past 5 years. I prefer Shoprite, compared to other supermarkets, for the low prices on certain food items offered. Lately the customer service of this particular store has become worse and worse. The cashiers are rude and unhelpful. One particular day, I was standing in a long line at a till and when I got close to it I was very rudely informed by the cashier that this till was for Sassa card payments only, now there was no signage anywhere in the store showing patrons that this till was for Sassa card customers only. People were standing around not knowing which till to go to. I then went to stand in a different line and was then approached by a staff member snidely telling me that there are many tills and why am I standing in this one. I then went to a different till (my third one) and again was approached by the same staff member and she led me to another till. The whole till situation took 25 minutes when my actual shopping only took 5 minutes. I also saw expired dairy items and the bakery items were stale.
