I'm sure it likely varies from region to region with better local management fostering a better environment and happier staff. Back in my previous home I passed Lidl, SuperValu and a Dunnes on my way home from work. Lidl was consistently the quickest in terms of getting through the checkouts, followed by SuperValu and then Dunnes, where every now and then the staff would stop for a chat before even acknowledging I was standing there waiting for service. I found the staff in Lidl were generally a lot less grumpy than the other two.Balderdash - I'm not imagining it. Dunnes etc don't have to open/close/open/ close checkouts because they're staffed adequately unlike Lidl.
