Disgusting service

Yesterday my husband and myself decided to go to mug and bean Newmarket to grab coffee and cake after work, upon our arrival we entered the restaurant and immediately the waiter said we are closing at 8pm no greetings no introduction nothing, and my husband said to him we just grabbing coffee I'm sure will be done in 30min cos we got there at 18:45, we sat he brought us a menu and I politely just told him we just want cake and will be on our way, he brought us our cake we ate and decided to leave, the whole time we were there he didn't even once come to check on us, we wanted to pay no 1 came to help us we went to the register to ask if we can pay there one waiter said he could assist with helping us pay, as we were about to pay the waiter who brought us our cake came out and shouting at the waiter that he was trying to ***** from him and they swearing at each other, I've never been so disappointed and disgusted, after a long day u expect service and peaceful time, please hire ppl who care about service and who like to treat ppl with kindness
