bell ends have sent my Tennis Racket out with the wrong grip size

Who the wombles employs these muppets
If i load a wrong box onto the wrong trailer i get pulled up in the office at work, i've not done that in a long time,
had a new picker last night working with me and he put 15 wrong boxes on for me across my Leland and Edinburgh trailers, 15 out of about 2300 is a lot to wombles up in 5 hours and a probable sacking, lucky i found them hopefully i didn't miss any
