Thing is, he got a PDf file from them. Copy/paste the thing, and than while changing colors (preparing the stuff for the screen printing, it have to be separated with every color in black on separated sheets) he missed to notice one letter in a word that was left in different color and was not printed with the rest on the sheet... Small mistake, but when you read like: company it was like: cmpany.
He read the thing once and his brain fucked him, because brain like to 'fill the gaps' so if you see cmpany it reads company, lol. Happen to me also, but since I always check the first printed t-shirt and spell the words like C-O-M-P-A-N-Y in front of workers that thinks that I'm crazy paranoid XD i manage to avoid mistakes like that. Especially when we got a big job like 500+ t-shirts.

You better read that shit at least 20 times and check another 30 times before committing to print it. XD

But, still, better to be called crazy paranoid guy than hobo...
