Insecure load? REALLY?

Just been sat at a haulage firm waiting get tipped.
Was an expo trailer there being loaded a double deck curtain sider he collected a full load.
Had some ibc tanks. Some builders bags full of God knows what.
2 coke vending machines strapped to a pallet

Anyway he had a full load of all sorts.
Pulled curtain closed and drive off.
Unbelievable.
And just to make it worse the driver was sat in his cab for about 30 mins while being loaded.

Didn’t get out to check or watch just sat there on his phone.
Got out shut curtains and drove off
