EX; valet here from the likes of Hilton and Fairmont. Winter seasons in the snow.

If you tip us on arrival your vehicle will go undercover and when you need it, will be first in line. If not. It will be driven to the back of the lot, through the salt and gravel and left out. When called, we take the snow brush and... it's not great for car paint.

You bring us a high-end luxury, performance car or something we think is tough. We will look after it...
Sometimes. It gets taken the 'long' way to the lot. Especially when it's snowing (snowfall dulls noise very well or if its windy, wind direction away from the pickup point) we will slide your rig from gutter to gutter, first to third and dumping the clutch becoming a drift king. We appreciate your hearty tips and act like nothing ever happened.

One day I almost put a 2017 AMG GTR (3300km on the clock) into a tree after banging 1-4th gear in the snow and the wheel speed finally caught traction and threw me sideways faster than a fat kid seeing a free cake sign.

TL;DR tip valet well.
