Bulk coal by tri-axle or trailer is a couple minute deal and they are going to expect that. Having said that even bulk coal from a delivery truck shouldn't take more than 10-15 minutes if the homeowner has it set up right whether its one ton or 10 ton. When I was running I was usually on a tight schedule, if you tell someone you're going to be there between 10-11 you should be there between 10-11. It's gets tougher as the day goes on, a guy driving a trailer or tri-axle is going to be a on schedule too.
I took the good with the bad but when I got a new customer I'd tell them what I would and wouldn't do it, basically if the chute didn't reach the bin at a reasonable height (e.g. it had to be few feet off the ground) it wasn't going in the bin and since most of deliveries were pretty far it was going on the ground if I couldn't do that. Didn't happen often because I always liked a challenge but I wasn't going to kill myself either. I'd always suggest how they could make it easier, simple changes can make a world of difference. If it was really hard I'd tell them to change it or call someone else. If you're spending more than an hour at house its too long.
Again if you're going to expect them to sit there and wait while you offload the coal into bags or anything else other than dumping it on the ground let them know what you want to do. They'll be able to adjust their schedule for it, tell you the additional costs or decide if they want to do it. If someone gets stuck somewhere for two unexpected hours the rest of the day may be shot.
