Visited Oink while living in Scotland a couple years back and to this day I am still upset at how I was treated.  We ordered their delicious sandwiches - but my cousin asked for extra sauce because her sandwich was a little dry for her taste - she even offered to pay before finishing her sentence. The manager (or owner) was so upset by this - she said \"you Americans - always wanting more\" and then went on a rant about how entitled we are.  We were stunned.  I told her that was an incredibly rude thing to say and she said we weren't welcome back. By far the most awful dining experience I'v ever had. I called later and asked to have my complaint to management addressed - never happened (which is why I assume the person who helped was a manager). Business does not care about their customers.  Disappointing to this day.
