Thanks for the tips - I may just have to try it!!!! I've never used egg in my mac and cheese - then again I've only made the sauce on top of the stove. I make a butter/flour roux and then start adding milk and cheese......cheddar, jack, blue, mozzerella, whatever I've got on hand. Then stick it in the oven. If I'm going to use a processed cheesed I use cheezwhiz, not velveeta, hate that stuff-too much of it as a kid!
As for the bank being wrong - I had a block on my account for a certain firm and the bank ignored it and pulled a large, totally unauthorized, amount out of the account - thus bouncing everything else I had written. I don't know if the bank wound up paying the gas company all of the fees and reconnect charges, but I sure know I didn't.
Good for you! I know the bank and gas company tried to bully you into paying. LOL from Georgia.
