If you were going for a professional detail you would be expecting it to be washed with snowfoam, and then the 2 bucket method, clayed to remove contaminants, paintwork inspected for depth of swirls and a suitable polish and pad comboto be chosen on that basis and then sealer / wax on top of that. I don't think any valeter at a dealership will or will do that, maybe not by choice but by Instruction. If it was me I would haggle a few free services or something out the dealer and take it to a pro to get it done right and don't let them wash it again and make sure they no not to wash it again!
