Sounds like a weekend in Sydney! Honestly most cafes selling coffee dont do it well, regardless of where they are. Because most cafes are flat keeping staff on $10 ph pay rates. They just take whomever comes along, show them how to push the buttons and hope for the best. :o Cafes who do invest in barista training often lose their trained and skilled baristas to more exciting gigs. Its a catch 22.
I know here in Sydney the cafes with the best coffee are often owned by the barista/\/roaster whos set themselves to earn more money than working for someone else could.
The whole impetus for me to spend a few thousand on a coffee setup at home was the difficulty in finding decent coffee out there at any price. I guess the UK is no different.
At least your gear was taken without violence or the threat of it. If I was going to lose my stuff Id prefer it at the skilled hands of a pickpocket than a thug. Small consolation I know.
