Went out last night with a friend. In a different town to usual so weren't familiar with the bars. Thought we would try somewhere that looked nice. I went to the bar and asked if they had any malibu. Bar man said no but we have 2 similar spirits. He handed me a bottle and said smell it to see if I wanted it. I did but it was a dark rum, not sweet like malibu which I fancied. I politely explained I couldn't really tell from the smell so he said try a shot. He then handed me an almost empty spirit bottle. It had literally a drop in the bottom. I assumed he was letting me taste it so I started to drink it and with no warning at all he grabbed the bottle out of my mouth. He banged my tooth and lip and shouted don't drink it! I was that shocked I just turned away and we left. I felt like an idiot at first but when nearly an hour later my mouth still hurt I was angry. I get now it was a misunderstanding but he hurt me. Was I in the wrong?
