"Do you know? We don't know"

It's really interesting how many people "don't know" things they probably should know. For example, yesterday, my friend, Elsie, and I went to Wally World to purchase a lot of ingredients to make cookie mixes for the local Street Fair. Neither of us were any good at trying to figure out how many bags of flour to buy to get 38.5 cups. We had to use a calculator to do some figuring. Not being a cook, I even had problems just finding the ingredients in the store, much less how much to buy when I did locate it. Who buys things in such bulk anyway?? We won't know until Tuesday if we actually bought too much or too little of everything. Elsie wanted to just feel the bags of chocolate chips and M & M's to see if she could determine if there were 3 cups in a bag. I didn't exactly agree with that notion but it made her happy to do it that way, so we shall see. (Glad there are grocery stores nearby if we have to get more). Then we needed to purchase wide-mouthed quart jars for the cookie mixes. The clerk in that section didn't know if they had any without looking. They didn't, so she said no one would have them now since people didn't can things in October! (What do I know? I thought you could use jars for holding more than canned tomatoes, green beans, etc. We still have some grapes coming in and there are delicious apples coming in now in the mountains. Can you use jars for jelly and jam?) Anyway, we did find plenty at a local grocery store.
Then I had to purchase new floor mats for my new vehicle. I found some that said they fit trucks and SUV's but didn't indicate if they would fit compact or large sizes. Of course, the clerk in that section didn't know either. When I asked if there was a catalog that indicated the ones suitable, he didn't know if there was such a thing. Fortunately, we had a tape measure and we did it the old-fashioned, but accurate, way. (Old-fashioned still works, too!). The clerk thought we were crazy to take the time to do that. He said "Buy them and bring them back if they don't fit!" Why should I do that when the vehicle is parked less than 200 yards away?
Needless to say, we had a fun time laughing at ourselves and others too. Can't wait to see if we did "know something!"
(PS The mats worked and looked GREAT!)
