Should you tip while at a British Pub? 

Absolute nonsense. No one tips in pubs in the UK.

Tipping is dumb.

Part of the clip was Manchester, glad to see Bloomberg getting out of London.

I think that the Freedom of Choice is not guaranteed in participation in this imitation game. The flow of information for making choices seems to be polluted.

No.

Tipping is a growing part of the menu in Europe. At many restaurants in Norway, Sweden, and Denmark, when they handed me the card payment machine, the first thing i see is the tipping option menu.
