Amusing service reminder postcard

I had a phone message from the dealer informing me I was past due for service. I thought that was odd since I had been over there two weeks prior for the 10,000 mile service.
A few days later I received a postcard from the dealer telling me I had about 10,554 miles on my truck so it was now due for the 15,000 service.
10,554 is how many miles I had on the truck when I took it in for the 10,000 mile service.

 

And.......what would that tell you?

 

I got one telling me to come in for my 10,000 mile service shortly after I was there for my 30,000 mile service. Same postcard, your truck has 31,xxx miles on it, it's time for your 10,000 mile service. Apparently numbers aren't their thing...
