Quick release skewers? Is there a right or wrong way?

[novocaine]

Trying to remember back to my Saturday job at the local bike shop days (circa 20 years ago!)... don't boxed bikes come with the QRs non-drive side from the manufacturers/suppliers?

They normally came with the skewers in a bag so that a set of caps could be fitted over the axle. the caps were useful as they fitted inside the shop stools legs and stopped it scratching the floor.
