Who'll Change The Light Bulbs?

I was closing up the shop tonight and I noticed some light bulbs need replacing. Since I'm the only one in the store that does those things, I couldn't help but wonder who will be changing the bulbs after I'm gone? As it stands now we have two men in the store; myself and a 78 year old part-timer. I know he won't be asked to climb to the top of a six-foot ladder to change the bulbs, and I can't see any of the women doing it. Not that women can't change a light bulb, it's just that one woman is very short and it would be a somewhat tricky and challenging task for her to do it, and the other, well, let's just say I can't see her climbing a ladder to change light bulbs. Well, someone is going to have to do it, 'cause I won't be there.
