Tesco Petrol fiasco in General Retail Posted March 9, 2014 · Edited March 9, 2014 by ims21 Your mate the mistake, not tesco. They wanted something they could enforce if your mate didn't come back. How do they know the van wasn't stolen. If your mate was planning to come back, as he did, signing would have done no harm. Don't see the problem. I agree with ihb.
