Well we certainly will not be shopping in JYSK if that is how they treat their customers, and as a fellow Irish Woman now living here, I am totally disgusted by the abuse suffered by you and your wife.
Obviously there is no Management in this store, and the staff who spoke to you should be instantly dismissed.
The only way to make them realize how much they actually need the "Irish & British" trade, is if we boycott the store, no sales - no wages. Like the old saying - Hit them where it hurts - their pockets !!!!!
