Needless to say Tesco have denied it, and you have to love the standard "denial of un-PC behaviour" statement:
A Tesco spokesman said: "Jedi are very welcome to shop in our stores although we would ask them to remove their hoods.
However, the Jedi was not convinced and said:
"I'll advise worshippers to boycott Tesco if it happens again. They will feel the Force."
Yes. Quite. Something tells me this isn't going to affect Tesco's share price.
