Right, I now have the full story.
I have spent all afternoon and most of the evening discussing the CISRS/Tesco Clubcard saga with the Leading Hand Trolley Collector in my local Tesco Extra as the Manager knew nothing about this (Apparently the Manager was useless as a trolley collector and only got the job because he sucks c.ock)
It turns out the more you spend at Tesco the more qualifications you can exchange your Clubcard points for.
After a bit of persuasion he showed me the CISRS/Tesco financial forecast for the next financial year, it was a real eye opener.
Every Polish lager has quadruple points, so does mayonnaise, every pickled vegetable imaginable, some weird looking cakes and loads of stews with funny looking dumplings.
This is so Tesco can break into the Eastern European market and succeed in the World domination it craves, but at the same time giving the Eastern Europeans more tickets than Jason Gibbs.
The trolley collector also told me he left scaffolding after 25 years once he couldn't get through the turnstile because his ECITB card had been withdrawn, a shame really as because of the financial strain they were suffering as a result of his card being withdrawn his wife left him and moved in with a guy from Romania who had a part 2 CISRS (Bought with Clubcard points)
I fear for the future lads...........
