My only point was to point out by dropping your price your in danger of
dropping all your price to keep the other accounts too.

Your competition can and will set traps for you to fall into,this will lead into a no win for you.If they can keep you busy washing for a cheap prices under a every small profit they have you where they want you.They will be able to use you and your low price when trying to get your other accounts.
Nomatter if a one man crew or 100's of employee's so many trucks can be washed by each.Why work your hindend off when you could be making more washing the same amount of trucks.Its hard to replace things in the long run with low profits accounts.....
Your competition knows you cann't go up now,your price is set for a long time and they know it.

When In Doubt Think It Out
