I recently had my front tire replaced. When I got home I realized the guy had put the tire on backwards. Since I won't be able to get it changed for several days, I'm wondering... how sketchy is this situation?
It was the front wheel that got the tire replaced so like you the tech did not read the information, no excuse part of being human right? 
"We are only human" is not an excuse for a mechanic.
If I was the service writer or mechanic I would write that on the ticket. "Came in WITH or WITHOUT wheel spacers" Drive side is the side with the sprocket or drive missing. LOL..lol Duh CB 750.... left side.
OK. Just the facts. I bought this tire on eBay, rim and new tire, to use on a pre-76 cb750. When I got it, I barely opened the box, other than enough to give a quick look at the tread and chrome. It came with a disc attached, so directionally, it was pretty obvious which way the tire should go. The tire I had on my 78 cb750k was getting pretty bald, so when I took the bike to get inspected, I brought along the tire to put on temporarily, until my new front and rear tires get delivered... Bridgestone Spitfires with the raised white lettering. I told my mechanic, a very competent fellow, to put it on, and that it was temporary. He actually did notice but told me he figured I knew it was backwards, it was temporary, and wasn't that big of a deal (plus he got to bust my chops about it).
Ultimately, I rode my bike in the rain on the highway and really couldn't tell any difference from the last time I rode in the rain with a nearly bald tire.
