We all make judgments about appearances.
I really enjoy drug user clients as they tend to be
more entertaining and 'for real' than vanilla clients.
But they have all been obsessively clean, well dressed and healthy looking.

I think you're very resourceful and clever.
I know it takes time to comprehend a 'bad' situation as it unfolds.
Perhaps you can make a little list of excuses for such times eg
water burst plumber, gas leak etc.
Then shut the door on them.

Whatever his issues, illness, drugs, self-neglect etc
His presentation means I don't want his breath in my face,
his body parts or fluids on my fabrics, linens ect.
Nor would I want to handle his flesh with
bare or gloved hands.

Hats off to you Cheffy....you're a soldier.
