Not necessarily. Many years ago we were climbing at Pen Trwyn mid-week. There was one other party at the crag. After they left I noticed a set (yes a full set) of Friends hanging off the Marine Drive wall. As we were heading out of Llandudno the pair were hitch-hiking. We pulled up: "What colour gear tape do you use?" I asked, "Blue" says one, "Yellow", "Lost anything?", "Err, dunno". At which point I held up the rack of Friends and the guy nearly fainted!
