I found a piece of meat in a 'vegetarian' option at a local cafe. I had taken it away and didn't want to go all the way back with it so I phoned to tell them and emailed through a photo. I got an apology on the phone from one of the staff and he said he would pass on the information to his manager (who was busy at the time). I had no reply to the email. I was in again today and the manager was serving me. I asked him if he had received the message and email and he just said "oh, yes." and that was it. No apology, nothing. Should I kick up more of a fuss?
