I'm glad you're sorted. Not a nice experience.
Put a chair leg through your bag strap.
I have way too much faith in human kind and several times on Sunday, I left an iPhone 11 and a brand new MacBook Pro on the table whilst I was doing other stuff/communicating with staff… granted it’s a pub in a nice, and slightly remote area of Malvern with mostly totally trustworthy regulars, but it only takes one wrongun, and it’s both expensive and hugely inconvenient.I was very lax, as I always am when it comes to security; a lesson learned.
