tank cover dropped

so I just got into the sense to drive car washing again and what happens? at the dry process there is once in the back right n light dull banging/noise… I don’t think about it anymore and drive out of the washing system, go around the car to fold out the mirrors again and see –> THE TANKDECKEL IS AT TROCKN’S FALL!!! O_o I of course right in front of the type of the cars with the Kärcher etc “pre-treated” and the problem described or demonstrated according to me I had my name and telephone number put in for the boss (which, of course, wasn’t there) with the statement of the “cleaner”: “the boss is in touch with you, everything will not worry…” now my fat guy is standing on the road with no tank lid… what I like at all… well, see if “chef” is coming in and how he is supposed to go on… even with 2 photos of my great tankdec kels
