Think of the fun you'll have dealing with the public...
A woman bought a brand new Riccar, then brought it back 2 hours later, she sucked up the cord into the vacuum, damaged the roller brush and cut the cord.
A woman brought in a Rainbow D3C for service, after cleaning it and servicing it, when she went to pick it up she kept saying this isn't her vacuum, hers doesn't have white stripes in the top section. Even though we showed her that the serial number on the receipt and the serial number on the unit match she still kept saying it's not her vacuum.
A man brought in a vacuum, after figuring out what's wrong and giving him an estimate, he doesn't want it fixed. So he picked it up. A week later he comes in with new parts that he bought online and wants us to install them at no cost.
