I am currently sat in Costa coffee inside the Tesco store in Haydock. There is a balcony with tables over looking the store and 2 tables free when I was served. 1 table was being held for a customer behind me so I asked to sit on the remaining table. I was told no because I'm a single person and that is held for 4 people. Bearing in mind there were 2 other empty 4 seater tables empty in the store, I don't see the issue. Firstly tables shouldn't be held for people they obviously know (first name terms), it should be first served basis. Secondly the server was being a jobs worth not letting a paying customer sit where they wished when the store is not busy. Not great customer service.
