Though not the London store, I've been rather frustrated with Apple Store employees here in Santa Rosa, CA.
When I called about Shuffles last week, they said I should come in on Friday. Came in on Friday, no Shuffles. Guy said to come by on Saturday. Came in Saturday, no Shuffles. Guy said to come in on Sunday. Came in on Sunday, was informed that not only were there no Shuffles, but they never get shipments of anything on Sundays. Called my friend the Apple rep at CompUSA and had him remember to email me when they get them in next week.
