In a shop just now looking at walking shoes. I was mid conversation with the sales assistant discussing waterproofing etc of shoes. Another customer butts in and asks if a different shoe is waterproof. Fair enough if she only wanted to ask a quick question. But she then proceeded to launch into a full on conversation, asking about sizes and generally ignoring the fact that we were there. I said, perfectly politely I think, ‘excuse me but we were being served first’. She then launched into a tirade of abuse calling me rude etc. Poor young girl serving us didn’t really know how to handle the situation but did turn back to us and carried on serving us. The other woman then called me rude again and said she would have just walked out but it wasn’t fair on the shop assistant as she had done nothing wrong…. I am sure I wasn’t in the wrong but it has made me question myself a bit! I was first! She walked into the shop after me. Was I unreasonable to call her out though?!
