Ghost sign above a cafe

I had some books to post, got on a machine, and then realised I’d mucked something up. The young chap who bailed me out was efficient and pleasant in equal measure. I’ve griped about the Post Office but the staff are ace.
     I then went to Tesco and noticed their ‘Meal Deals for 2.’ The seared chicken and mushoom risotto looked nice, so I chose a side and a desert, but passed on the drink which all seemed to be fizzy bottles. At the till a lady who is always very helpful said I’d need to include a drink to get the £10 Meal Deal. I said I didn’t want one. She rattled off the available drinks and when she said: ‘Wine.’ I said 'yes please.' I got a bottle of Sav Blanc which apparently retails at £8:50, plus all this food for the princely sum of £10.  I wonder if looking like a dithering idiot is working for me?
     The picture is of a ghost sign which the proprietors of The Original Milk Bar have retained. I applaud them for that.
