Do not touch

My family and I frequent Paul's ice cream in linksfield as we live close by, but never again after today. I went with my son this afternoon for an ice cream. While in the queue to order, we both noticed that there were 2 silver faucets on the counter. One was pouring what looked like white chocolate into a dustbin, the other was pouring brown chocolate onto the same dustbin. The faucets were literally 10cm from where you stand in the queue. There are no signs to say "do not touch" or anything like that. So with the fact that they were pouring the chocolate into a dustbin, my son put his finger through the stream of white chocolate and licked his finger. There was a family in front of me with young kids. The person on the till then starts screaming at me and my son for touching the chocolate stream. IT WAS GOING INTO THE DUSTBIN. I asked where it said "do not touch", to which she responded that I will now pay double for our ice creams because the stream was touched, before it got thrown away in the dustbin :) So with all the screaming in front of small kids, I walked out and spent my hard earned cash at a different ice cream shop. Last year there were 2 very friendly and helpful ladies behind the counter. I see this year the company has gone for 3 unhelpful poor mannered assistants that don't want that job.
