Come on Silvan, we musent have style or personality. We must be bland so as not to offend the most sensitive among us.
Bullshit.
Having worked in shipping and receiving I can say A to Z is not an understatement. Common carriers and cartage companies carry everything. I've seen 'substances' on the floor of about every trailer I've been in. Packages rupture regularly. I've also had materials pass through the department that I knew were mis-marked (such is the nature of government contractors). Then there is the dust from tow motor tires that have driven through the plant picking up God knows what.
I once received a shipment of slightly leaking sacks on a pallet marked with Scull and Cross Bones and also marked 'food grade'.
Mayhaps you don't even want to be near the sawdust from some pallets.
