Sinister: what does it all mean?

[superbob]

hey. 
alright i've figured out that debenham's is some sort of department
store, no? and i've figured out that leccy = electricity.
but, i can't figure out this one other thing because i guess it's a
european thing.....what does "turning tables round in marks and
spencers'" mean. what is he referring to?
