Yes, infact I try to be as much of an arsehole about it as possible.
The reason is - id rarther be the arsehole with money, than an arsehole without.
I sign for about 5 parcels a day on average due to running a small business, and I know what is coming and who its coming with.. Dependant on what it is, I will come outside (so the parcel hasnt been delivered) and open it outside and if I dont like it, I just refuse it.
The delivery drivers are in a rush and if I can appricate that, they can appriciate I dont want to get ripped off.. On occasion they dont appricate my appriciation very much, and throw temper tantrums - I have had to shut the door because he was trying to deliver the parcel once, and then he left it against the house and I had to run out and put it on his van roof because I didnt want it - hot potato anyone?
