Went to Cinnabon at Sandton city, we were treated eith such disrespect and ended up leaving the store without being assisted because everybody ignored us. There was a guy taking payments and he ignored us n took a call. A video call while we were busy ordering n left us unattended. The other one came to help n we asked for the manager n he said that one who is on a video call with his girlfriend is the manager n unfortunately there's nothing you can do. We left the store without being assisted still n ended up buying doughnuts next door at Krispy kream
