Waitrose comes out tops for quality, according to Which?. Lidl and Aldi rate high for prices. That means then that they are not very good on quality, which we all know anyway. You are right about the hello, thank you and goodbyes. It is the same in any of their stores I have been in. Must be the pressure they are under or they are out of breath from rushing everything through their checkout too fast. Not a customer friendly company for sure. Certainly not an older/ less able friendly one. Never mind. We know what to do don't we.
