It is better to have a mannequin at the entrance to the store than an Operations Manager.

On August 25, 2020 I went to the store to return empty ink cartridges for recycling. The store gives you a $3 off coupon on each of them for next purchase. On this day I had 5 cartridges. The coupon says that it sets a limit: 3 cartridges per customer per day. I was with my husband. That s two customers. I don t know why but a cashier was outraged for some reason. Well, omit this situation. What happened after that was even worse.
I took 5 items and had 5 coupons. The coupon says it sets a limit: one coupon per purchase. Therefore, I asked to do 5 different transactions for each item. The cashier became outraged again saying that I could use 1 coupon per day. I was confused. Why is it 1 coupon per day if it was allowed to use more last time? I told the cashier that he might be wrong and asked him to call the manager. A man came up to the cash-desk with the words: one coupon per day, ok? And simply walked away. I was like who is this man? He didn t introduce himself, he even didn t ask what had happened. I asked what his name was at his back. Without turning to me he said his name was Peter and continued to leave. Honestly, this is so disrespectful towards customers. I would like to remind you, Peter Donoghue, that you have a job because of the store s customers. For now, it is minus 2 customers on our behalf, but if the store staff continues to treat their customers in such a manner, I am sure it is going to be fewer. Nobody likes rudeness.
Returning to coupones, I don t understand where logic is. I could leave the store then come back to another cashier and spend all the coupons I need in the end. There isn t any record of when I spent the coupons: today or not. Especially in my case, I took 5 items and asked to do 5 different transactions, not apply 5 coupons for 1 transaction.
What I want to say by writing this review: first of all, if the Operations manager can t deal with any situation happening in the store, there is no reason to have such a manager. Or maybe it happened because he figured out that I was a foreigner and he didn t feel that he had to spend his time talking to me? And, secondly, I would like to get a response on how these coupons work indeed? Despite the fact that I am not going to come to this store any more, it might be helpful to those customers who had the same question and the same problem in the past.
