gotta practice a little tough love. make sure you tell them dinner will be served at a specific time, then enjoy it without them and put it away right after you eat and when they show up NO RE-HEATS. that should get the message across. we did it to my Mothers bro in law and it was a little uncomfortable, but it never happened again. just tell them flat out your not gonna get stressed out, ruin/overcook your meal beacause they are too inconsiderate to show up on time. my wife is a chronicly running late type and I always tell everyone that and not to hold dinner or anything else for us.
Nachos correct.
I have had friends family do that when I'm taking them fishing. Well now I leave and do not wait. I have also told them. If this happens and there no phone call and or you not racing to the boat ramp, never again will you go or be invited.
These are the same people that were so late to our wedding rehearsal they all together missed it...and caused my wife to be late to the wedding the next day.....seriously
I usualy start the countdown with my wife at T minus 60 minutes with updates every 5 and after 10 years we are always 15 minutes or more late for everything. now I just figure it's less time I have to spend doing something I don't want to be doing in the first place, unless it's something I realy want to do and will then flat leave her and let her take her own car and be ready for hell week when we get back.
