More travel than flying
Twice forgotten laptop charger. Now carry a travel one in my backpack
Once, had a nice hotel with hanging space hidden behind bed. I traveled from Limerick to Belfast before realising that I had forgotten to pick up a week's worth of clothes. They were very good at posing them back. I went shopping in Belfast.
The hire car in Dublin that froze my phone. Had to find an apple shop as I could not google how to do a hard reset.
The Mercedes B class hire car in Aberdeen that had a USB 3 socket. Not convenient. Oh and it had lane assist which would try and throw you off the road if you cut the centre line on a corner..
