you told them your price and they have declined it, why are you going to have a look?
I have a very low opinion of letting agents they have no respect for your work or time, they see you as a lower class person who should jump when ever they call.
what makes me laugh is the person calling you is at best the manager ( usually one of here juniors) who probably earns half what we earn and has a decidedly lower standard of living but she has the audacity to look down her nose at us when really she is'nt good enough to lick the dog dirt of our shoes
You must know some of the agents round here then

We had one a while back that we did quite a bit of work for and for their tenants on a private basis. This one job in particular (private basis, but picking up the keys from the agent).
Arrived at agency
"can we have the keys for....."
Agent: Sorry can't find them (Uhhhh?!!!!)
Spoke to customer again, who clarified he left the keys with them the a couple of days previously, with our payment sealed in an envelope as he had moved out.
Passed this on to the agent.....blank faces and went off to search again.
Meanwhile I shot back to the van (outside the house in question) and for some reason thought lets try the garage door, it was open, as was the door to the back garden and then the door into the kitchen.
The agent wasn't even bothered and couldn't care less.
Any way to cut a long story short,
Keys and payment turned out to be locked in safe in managers office.
Did clean, went back to agent, he said manager due back in 10 minutes if you want to wait for your payment. Ok fair enough.
20 Minutes later, no manager and getting close to our next appt. No problem we are still in area, will pop back later and get ££. This agreed with the guy in the office and manager over the phone.
Went back to the message that manager has decided not to come back to this office today. I phoned him and asked when will it be convenient to get the money, and got so much abuse it was unbelievable. He actually said that we would get our money when he was ready (it was not his to withold) and that if he decided he wouldn't go to that office for a few days, then tough on us.
Charming

He carried on saying that if I didn't hang up, then he would be extremely rude to me and he wouldn't be responsible for his words or actions

bad hair day or what?
I just said when do you plan to be in that office next, then we can amicably arrange a time to collect. He went off again on one and in the end I just said, look you need to calm down, i'll call you tomorrow and we'll arrange something then. goodbye and hung up.
The words weren't used, but the inference of "you don't matter. you're only cleaners" was there. Got money eventually and had the pleaseure of telling them that in the future we will only deal with their tenants on a private basis and will not do any more work for them direct. We know the lady that does the general cleans for them and 3 weeks ago, she had enough and told them where to stick it too...good for her
