After many many years of praising Costa Coffee today was a horrendous experience at their Terminus Road, Eastbourne house. This is not to be confused with the newer establishment opposite Eastbourne Railway Station. Over the visits you expect to have a few words with the staff and we have always found them to be friendly and with great customer service skills. Today we placed our order and were chatted to by the lady barista. My wife is very unsteady and in unable to carry the drinks so I always do it.. The coffee house was nearly empty so she headed towards the rear of the house. The male assistant pulled a chair ahead of her to block her path. He then instructed her to sit at a table closer to the counter. This was done in such a loud way I thought someone was shouting at her for some reason. The same man throughout our visit was literally shouting at customers to avoid the area he was concerned with. I noted that despite the female staff member being really bust and taking order and payment and serving the refreshments the male just continued shouting. As the toilets were in the no go area I asked if it was okay to walk down the right hand side of the restaurant. He then shouted, "use the second toilet on the right" I said to him, 'Thank you. I know and so does everyone else in here now'. We were amazed that two children were in the area that was clear of customers until we realised they were his children. He asked the female staff member to provide drinks for 'his little ones'. We had decided that instead of a relaxing time over coffee this man thought it was fine to shout his head off. We even know he had bet £50 today for England to with against Scotland with a score of 3-0. This was the worst experience of Costa Coffee and in fact any coffee establishment it was appalling! After all these years we have decided to take our custom elsewhere. I have given one star for the service at the time of ordering. This male staff member needs to be aware that some people are slow moving and mat be disabled. He obviously either thinks customers are deaf or are interested in listening to him tell his children and customers off and for him to share his knowledge with everyone when most people just want to enjoy a relaxing few minutes with a good coffee. Time for us to move on. I stress the lady in Costas was friendly and ensured we had complied with their Covid requirements.
