My local Sainsbury’s convenience store had a strict policy of limiting the numbers in the store but that seemed to disappear as soon as the mask policy was announced i.e. a couple of weeks before it came into force.

Thanks for the personal observations.

There's a new summary of the reported behavioural effects of face coverings:

"Is risk compensation threatening public health in the covid-19 pandemic?"
Mantzari et al (2020)
https://www.bmj.com/content/370/bmj.m2913

Their "Key Messages", in full:
"Risk compensation—increasing risky behaviour after adopting a protective measure—has been used to argue against public health interventions, such as face coverings to reduce transmission of SARS-CoV-2
Available evidence does not support concerns that wearing face coverings adversely affects hand hygiene
Evidence from other areas also indicates that risk compensation is not discernible at a population level
The concept of risk compensation, rather than risk compensation itself, seems the greater threat to public health through delaying potentially effective interventions"
