To collect someone or to pick someone - UK English
I heard it yesterday, straight from the horse's mouth, from a UK native speaker receptionist, laud and clear:
Someone is on the way down to collect you.
Also, couple of days before, one the first round of my interview, she also used this simplified version:
Someone is on the way down for you.
..useful in case you want to bypass the dilemma.
