I just treat clients and potential clients how I would want to be treated by an LCO. and to be 100% truthful and honest clothes is the last thing I'd be concerned with.
if I'm paying someone to service my lawn I'm paying for the quality they do in servicing that lawn, not to look good while they are there for the short amount of time once a week that they are there. they can go naked for all I care. as long there quality is what I want and expect.
