No, I'm afraid you were in the right place, just too soon.
I was planning on coming at 16:30. here
but I had some problems with a flat tire and had to visit 5 bicycle shops until I could get a single (!) 20" tube (wanted to buy at least 4, but only 1 piece left).
and I needed this tube 30min later when my valve slipped and the tube burst.
so I wrote here that I can't come until 17:30 at the earliest.
