Not sure if you're being serious about the "Really Mazda? Did ya not have people try this thing out before you approved it? " part, but it has nothing to do with Mazda.
Some company that makes corporate apparel and other things like coffee mugs and keychains sends a pamphlet to the dealer, a manager picks what he wants and the company puts the logo on it.
Well, I think we're all just having a good chuckle here about travel mugs, so don't take it too seriously.
I know I was only having fun with my left handed mug remark, but anyway.....to answer your question half seriously,
I worked in the corporate world for many years, and we used to buy stuff like this to give to our employees and customers as well.
There was/is a lot to choose from, and you just added your company logo to whatever you bought.
So,....if someone at Mazda picked this particular cup from a choice of many, then the choice of mugs does have something to do with Mazda.
Obviously Mazda didn't make them, but someone made an executive decision to buy this particular model, so yea, Mazda does have something to do with it.
Personally, I buy the cheapest travel mugs I can find at Wal-mart, and then promptly lose them or leave them behind somewhere.
I also have an extensive collection of mugs and lids, none of which match up.
Lastly, I have a tendency to put them on the roof while I'm loading my car/truck, and then driving away. Lost/broke more than one that way.
In the long run, take out cups from Tim Horton's seem to work the best for me.
Cheers all.
