With one way systems, social distancing, people queuing outside AIBU to wish people would make an effort to move as quickly as possible up and down the aisles.
Standing for ages deliberating between products, phoning your oh to check what brand of marmalade they prefer, or standing for ages checking a shopping list in a narrow aisle where people need to pass is inconsiderate.
These aren't normal times and most people have adjusted the way they shop accordingly.
But you still get the oblivious faffers and delayers.
