Visited M&S cafe at kings ditch cheltenham. Entrance blocked by assistant wearing hair in bun. She was filling drinks cabinet & made no attempt to move her trolley to allow access. When we asked if Cafe was open she gave a. Surly "yes" & finally moved trolley. There was only one person in queue but it took about 10 minutes before we were served. The tables were littered & were not being cleared. Being pensioners & vulnerable to Covid19 we wanted one on the outer edge to feel safe. After idly chatting for some time the lady with hair in bun sauntered over & started clearing tables for 4 in middle of cafe. I politely asked if she could do the table for 2 I was standing by on the edge. She rudely said "no there are plenty of other tables". I waited patiently. After clearing the middle she then purposely proceeded to the other end of the cafe to us & started cleaning there. As our hot food was going to go cold we were forced to go & sit at a table near the exit which meant everybody came past us on exit. The very thing we tried to avoid in order to stay safe from Covid19. Having been a loyal customer at M&S for many years we will never visit again. We know M&S are not doing well so can you explain why with so many good unemployed people M&S wish to risk their business still further by having staff who are doing just that.
