I don’t understand what this means? I understand that they bumped the price. But I du not understand what is meant by it being for the assistant? Care to explain?
The 'that was for my assistant' is just something they say to explain away the earlier quoted price. They are pretending that what they said wasn't the quote for this conversation, it was for another, different conversation, between the salesman and their assistant. This only works when the assistant is not in the call.
Electrician: "Okay, so my services start at $100/hr"
<nobody bats an eye>
Electrician: "... for when my assistant can handle things."
Replace Electrician by whatever skilled professional you prefer.
You price it at what you think works. There is no push back, so you make room to push the price higher.
You were happy to do it at the original price.
