Supermarket Sweep

 I've done a rough survey of supermarkets over the last week:

• Waitrose - virtually everyone is wearing masks.
• Tesco - about 30% not wearing masks.
• Lidl - 50% not wearing masks.
• Aldi - very few not wearing masks - less than 10%.

Now I don't attribute all these results to socio-economic group, but it does seem that supermarket prices drive the mask wearing and the more wealthy (and therefore middle class and educated) the clientele is, the more they will wear masks, No-one can demy that Waitrose, being hideously expensive, is frequented by those more receptive to sensible advice.

The outlier in this survey is Aldi, which is an alternative to Lidl, but we don't have one in Yate. The one I visited was in Thornbury, which is predominantly and staunchly middle class and will skew the results. which could be the reason for the high levels of mask wearing I saw there.
