Previous warehouse I looked after decided to get some clamp equipped trucks to store new white good's in the rack.

Suits from upstairs came & measured up, decided exactly what they wanted, came up with some plans & had a company come in to install all the new racking to the plan they gave them.

It all went horribly wrong when they tried to load the rack & realise the suit who had measured up had forgot to take into account the extra width of the clamp blades & also that the clamp need's to be opened slightly to drop the load.
The gap the suits had stated on the plans was just for 3 item's width without any extra space for the clamp blades, all the racking had to be dismantled again & reinstalled after the suits adjusted the measurements.

The only people laughing where the racking company as they got paid a 2nd time to come back & put the suits mistake right.
