Just had the opportunity to check out the newly opened Tesco Metro yesterday. Because our dinky part of London had no proper mid sized supermarket since Safeway/Morrisons closed shop 8 months ago, it was a relief when I found out that a tenant has finally been found to occupy the previously empty plot. No need to purchase groceries from the local but expensive Marks & Spencers any longer.
Already the cashier I found the be a lot more friendlier than the Morrisons one (the one where they harassed a scruffy twenty something guy for an ID because he looked "too young" to buy booze). Apparently they have been handing out vouchers with up to four quid off purchases, which I didn't have (nor did I know of), but she was kind enough to obtain a spare voucher and took £4 off my tiny £8 groceries, without me asking! That is what I call excellent customer service. Seeing that they also sell games, that £4 voucher would certainly come in handy.
