When I worked on a helpdesk for a company that supplied robotics for a Dark Warehousing operation.
Me: Hello, Company X helpdesk, How can I help
Customer: Your ****ing robot has stopped working again
Me: OK, Try removing the poster advertising the departmental football match off the wall again so that the robot can read the bar code and know where it is please.
Customer: There is no poster on the wall, Staff are told not to put them up.
Me: OK, Based on previous calls from your company, please remove the poster advertising the departmental football match off the wall again so that the robot can read the bar code and know where it is please.
Customer: Your robots are ****ing cr** they are always breaking down.
Me: Looking at the previous logs from your company, this is a common problem and the despatched engineer simply removes the poster.
Customer: (lots of ***** and ****)
Me: Well, I can dispatch a enginner and if it is found to be a user fault, you will be charged accorsding
Customer: Lots more *****s and ****s
Engineer duly dispatched and next day the first task was to issue an invoice for "Removal of user generated media preventing robot to operate in an efficient and effective way"- translation - The field maintenance guy walked into the warehouse, went straight to the wall and removed poster advertising football match of wall, to which the robot started up and carried on.
