Store number is 5871 Newport Express store. I went in on Sat 14/11/20 about 2pm and one male staff member was being really disrespectful about another female staff member, he was slating herr to customers. I found this so embarrassing and not the way tesco staff should be behaving this way in front of customer and on the shop floor. I did not know which way to look and was so horrified that that I have not returned to the store because if this member of staff could do this about a colleague what is he saying about Tesco's customers. This behaviour is very disgraceful, very unprofessional not befitting a tesco staff member.
