Where I live (semi rural, small town, low covid rates) people are very compliant. I rarely see anyone without a mask shopping, the odd one or two in the whole time they've been made mandatory.
Today I went to visit my parents, they live in Birmingham, close to Sandwell and Smethwick, high rates of covid in these areas. After my visit I popped to their local supermarket en route home and noticed lots of customers, around 20-25% not wearing face masks and thought it's no wonder there are high rates with compliancy so low.
