Bikes tend to be better behaved in front of a mechanic, & on a repair
stand where they aren't dealing with rider weight & road friction.
New gear cables will stretch, especially the long ones needed for a
tandem. I suggest you return to the shop & ask the mechanic to go
for a ride with you & adjust the cables on a test ride. S/he can
show you which adjusters to use when this happens again, and it will,
probably several more times. It takes a few miles for cables to set
into their final stretched position.
