Broker question

Have another situation here.I took a load to the east coast with 3 deliveries on it, an overnighter. Paid well at almost $4 per mile, all miles. The stipulation? Must give that broker shot at first reload home. The reload: 3 pickups delivering home for about $2.50, all miles.The load going out is to be delivered all on Friday, and it was without any problems. The problem? Reload is scheduled for same, 3 pickups also on Friday. I tell them this will most likely be impossible and they say go ahead don't worry about it. I get one pickup done and it is 6 pm, the other 2 pickups are to be done Sat morning and deliver Sunday morning. OK. I get to receiver and he is about 10 feet in the air over why I was not delivering on Saturday as promised by the broker. He does not want to hear any bit of my story. Consignee now puts my name into the mud, not the broker's. This broker has pretty steady, good paying freight. Only problem is, it almost always turns into a ******* nightmare and if anything goes astray from 100% perfection they make it look like it is completely the trucks fault. I have another broker who I get steady work from that the pay is right in line with this guy's, also they pay very quickly, both are COD if I go to their office otherwise I mail it in and they mail me a cheque and I am paid within about a week, tops. Do I take the *slightly* lower paying, "easy" freight, or do I continue trying to get the highest dollar while attempting to make the impossible, possible???Note: I do not extend any large amount of credit to any one broker. If they are slow to pay then I branch out to others. I never put too many eggs in one basket.
