A quick welcome back to work from the UK 
I always knew British cars to go “bzzzzzzzzzzzzzzzzzzzzzzzzzaaaaaaaaaaaaaaaaaaaaap”
…being that British cars sold in the U.S. were known for electrical problems.
USA Prices:
“If you watch=$75.00 an hour”
“If you talk to us when we are doing it=$100 anhour”
“If you assist us=$125.00 an hour”
“If you did the work before us=$150 an hour”
My mechanic’s sign reads:
Labor - $40 per hour (Depending Upon Your Attitute)
