Social Shopping at Sainsbury's...

I have lived in Kingston for 5 years and have always shopped at the big Sainsbury's store down in Sury Basin...but of late, it seems to be where I bump into/catch up with all the people I haven't seen for a while! And because I'm usually dashing to get away before my parking ticket runs out, I always leave abridged conversation behind me with a promise to catch up soon.

I know that there is a cafe in the Esporta gym but it such a pain to have to reorganise the parking ticket and there's nowhere else that I know of close by with parking (without going into Kingston that is).

I'm not sure I even know how this would work but it would be great to be able to extend a ticket already purchased...particularly if you could add coffee purchases to the 'parking fee' redeption total...
