How about drinking water in Xi 'an Jianzhong?

When we were in school in our freshman year, we agreed that all the buckets in the water dispenser would be returned in the end. At first, it was good. Then we didn't deliver it properly. I called one day in advance to make an appointment. The water delivery man forgot to make an appointment. I don't know why. Later, they threw the bucket at the door to see when it was his turn. Now the senior agrees to return the water dispenser bucket or something to me. I said you said you wouldn't refund the deposit. I said we can still drink your water later. They said I could only complain about you. People say I just hang up. If it is an individual phenomenon, it means that the management of Jianzhong is sloppy, so every water delivery person will be sloppy because there is no limit, so don't decide.
