In Lidl yesterday, two tills open out of maybe six, with long queues at both, we joined the end of the queue of one. After a long wait, we got to begin plonking our purchases on the conveyor, at which the woman on the till announced she was closing for a break, with the announcement of an alternative till being opened. The entire queue had to move to a fresh till, us expecting to at least be dealt with she refused and told us to go join the back of the new queue.
One person in the queue was complaining that this had happened to them already in this visit. How do they get away with treating customers like this? If they know they are going to be closing a till, why don't they advise people attempting to join a long queue and at least deal with those already having queue up.
Instinct suggests, that the way for customers to defend against this treatment, is to just abandon their intended purchases and walk out.
