The shop I worked at in Scotland never paid for any of the licenses but after 3 years we started getting calls about it. Big fines (very big) threatened and rather than pay for a license the boss just made us all switch off the tv/music.
We used to use it to watch the Tour/Giro etc. and I think the cost of the license would have cancelled itself out with people coming to the shop to buy stuff just to watch the last hour of the day’s stage.
After the music was turned off morale went down, and work definitely slowed. It definitely did more harm than good,and the workshop wasn’t behind a closed door so couldn’t even have it there.
The boss backed down to their demands as a restaurant nearby had been crippled after a £15,000 back-dated fine and license bill. It just didn’t seem worth risking.
