We did a cabling job for a customer, who did not specify how he wanted things terminated. Finished the job using 568A and their "IT professional" made us come back and reterminate the whole project B because "none of my computers work. I have B patch cords and you cannot mix them." He then proceeded to Google network wiring standards while he was lecturing me. Just smiled and nodded, reterminated everything, and sent them a bill.
Why would the it guy say it doesn't work? He can say he doesn't like it...or whatever but if the cabling is A on both ends..workstation and patchpanel then it is no different transmission wise from B, just transposed pairs. Makes no sense. The guy wouldn't know the difference unless he looked at how it is terminated.
