Dissapointment at poor customer logical service

I ordered a starter. There was no supply of my choice. My pleasant waitress informed me of this. I asked her if she could discuss a substitution with their manager. Apparently not<br> I was told sorry u need to choose something else. Oh well. Such a let down guys. I might be 1 customer but I certainly wont be returning. I will also give my views to prospective patrons.
