Archie could have kept his job....

...and still run the bar, at least until he knew he could make a go of it. I've known people who own their own business and still work full time as a safety net. The logical and practical thing to do was use vacation time to get things in order, and what Archie did on his own time was his own business. Sanders couldn't have done anything about it. Once the bar was re-opened and things were running smoothly, Archie didn't have to be there every night from opening till closing. He should have treated Harry nicer, and even made him manager with a pay increase so Archie wouldn't have to be there all the time. Harry knew what needed to be done. Since the bar was in walking distance to his house, all Archie needed to do was pop in for a few hours every night during the week, to make sure things were okay. He was just a phone call away in case Harry needed him. Hire an extra bartender in case Harry needed a night off. Archie could have also used the weekends to hang around and see what was going on, again, he didn't have to be there all the time to make sure things ran smoothly. But then, Archie being practical and proceeding with caution doesn't make for good comedy, does it?
