If, as a giant corporate entity, your employees are getting wide spread abuse, you need to look at your company and assess why so much anger exists. The problem is likely rooted in Tesco treating it’s customers like shit whilst they are living through an economic crisis.
Yes, somebody who snaps and draws a weapon is ultimately in the wrong, but with the numbers of customers Tesco has there was always a good chance somebody would snap.
I mean, Tesco and others are being scrutinized for price increases beyond those justified by increased costs of of manufacturing. They harvest their customer’s data, or make them pay more. They discontinue larger “bulk” size of goods, forcing people to buy smaller more expensive sizes.
I’ve now found that the difference between a Tesco shop and a Waitrose shop (the other one I have locally) has become much smaller, and I get higher quality produce. Asda, Lidl and Aldi are much more worth the trip now.
In my opinion Tesco have used Inflation as an excuse to go to town on price rises.
