Ha ha ha, I will, I might get a coffee and sit and watch, you can study the 'baskets only' queue from the in-store café, probably get most of the anxious ones there as can make a quicker exit (at least that's what I usually aim for if I can manage without a trolley-load). It really will be interesting, I'm usually head down and looking inward if you know what I mean dealing with my own anxiety, tomorrow I'm going to look at other people! x
