Tesco's Cheapside Manager Alan is an Ape!

I bought some Bahlsen biscuits marked on special earlier this week and noticed that the till price was £ 1.03 compared to the £ 0.79 on the shelf. I noticed while doing a self-service check out that the price was wrong and a member of staff corrected the price back to what it should be. Today I thought I would see if they had bothered to fix the error and bought the biscuits again but sure enough the price still came up at £ 1.03 in the check-out despite the shelf price still being £ 0.79.
I insisted on seeing the manager (Alan in the Cheapside Branch in London) who acted in a surly manner and just shoved the £ 0.24 owing and my receipt at me. He was upset because he thought I should have just called another checkout supervisor and had them correct the price while I was checking out. When I explained that it wasn’t my job to correct their prices when I have already told them that they are wrong and said I should have been given an apology for this attempt to rip me off, he got surly and told me “there is a Marks and Spencers nearby – go there in future”. When I said I would report him he then started telling me not to come back to the store and was yelling at me as I left the store.
Clearly staff training is a low priority at Tesco as is correcting “mistaken” prices – especially given that the new price-correction only policy now makes it a very lucrative business.
