The ushering staff in passport control area upon arrivals have become extremely racist, rude and unhelpful over the last year. They pick out Brits who are non-white, and question loudly whether they are British. No non-british would queue in the most ginormous queue for fun and giggles! Need leadership team to address racist, unkind directions. Ushering staff are not needed at all, if there are clear signs at the beginning of the zigzag lanes. Ushering staff only need to answer questions if help is asked for, not there to upset non-white Brits returning home.
