you white trash alamist crack me up, tell me what they are saying again at the truckstop you work at.
You don't end a sentence with a preposition. It makes you look stupid. Just sayin'
Just for the record, even though you posted a year ago:
You are wrong.
Ending a sentence, or phrase, with a "preposition" is perfectly valid.
First, when it happens the "preposition" is usually a particle, helping a nearby verb, like "put up with".
Second, you can even end a sentence with an actual preposition, as long as you avoid certain awkward situations.
What you should have complained about is that he started and ended the phrase with the same word, "at", that redundantly served the same function. That was, indeed, awkward, but it's not the fact that the latter one was a preposition that was problematic.
