Im not sure if im being unreasonable or not but this really irritated me this morning. Myself and an elderly relative went to a very popular local cafe. It has less tables and chairs inside than it used to because of covid regulations and it also has tables and chairs outside but these were unusable this morning due to the pouring rain. The cafe was very busy and we waited for around 20 minutes for a table. During the time we waited there were at least 3 tables of people who had finished eating and drinking and were just sat there chatting. These people could see that there were lots of others waiting for tables but just continued to sit there chatting the whole time we were waiting and while we ate and were still sitting there when we left! AIBU to say this is really really rude and selfish? They can see others were waiting and they kept tables from being used, i also think the cafe manager should have said something to them.
