Parking Dilemma #2

Yesterday I got back to the car park and all of the cars once again had notes on them.  The message these notes carried on them was this-

'No parking this week as we are cleaning the drains and your car may get damaged' 

After the clamping warning last week why are they now being so polite as to let us know ours cars may be damaged by drain cleaning.  To me this doesn't add up.  I have two theories- that the employees of the bed shop just think it's hilarious to wind us all up or that someone else that parks in the car park is winding us all up.  Yesterday the car park was pretty full but this morning, after the mysterious notes of yesterday, there was only a couple of cars in there. No doubt by tomorrow we'll all be back and I shall be on tenterhooks waiting for the next note.....
