A couple of days after our move out in June, we had been indoors all the time getting sorted and wifey said, "we're too tired to cook, let's walk down to Bar Llenair and have a snack".
It was a little windy outside, and I was wearing the cut downs I had on all day from our labours. David and Pepe had no problem with my somewhat relaxed attire, but when I got up from the table to pop to the loo, the lady at the next table said quite loudly "look at his shorts". I wanted to say, "Look luv, tomorrow I will be wearing better trousers, but you'll still have the same face", but thought better of it. (thanks to W.C.Fields)
Short sleeved shirt and clean shorts are pretty much OK for anywhere. I would always dress up a bit for places like Balaixa,
Stay, Can Cuarassa, Trencadora etc.
