In Udon Thani I forgot my new pump in the supermarket trolley and when I came back an hour later nobody had seen it – if they ever understood what it was about. I spent the whole evening looking through hundreds of trolleys without luck. So the following day I rode 40k around town looking for a new pump and after a long search (mostly for shops not located in accordance with google maps), I was lucky to finally find a small foot pump that worked, though it’s poor (plastic) quality so I have to be careful not to break it.
