Hey, I think your wife and I used to work together! I came to the conclusion that some people just can't see past this week, and they don't understand that you cannot spend every penny you earn.DW had the same thing. In the early 90s, she worked retail. On payday, many of her coworkers would rush out at lunchtime to cash their checks so they could afford to eat lunch that day. She, on the other hand, had direct deposit and didn't even know that it was payday because it simply didn't matter to her.
The same coworkers bought sodas from the vending machine in the break room once or twice each day for $.75 each. DW, on the other hand, brought a can of store brand soda ($.10 each) from home. The coworkers ate out every day, spending $5 or more on fast food. DW packed lunch from home for $2 or less. She was making no more than them. We weren't married yet and I was still in school, so I wasn't making much either. They just didn't get that you can't spend every penny you earn as soon as you earn it.
My husband and I were just married at that point, and I was still in college and was working just in the afternoons. We were VERY poor, having just spend almost every penny on our wedding and the downpayment on our house. We watched every penny carefully -- my grocery budget was $35/week for two people, and that was in 1990. Yet we put my every-other paycheck into the bank because we didn't yet have an emergency fund, and that was a priority for us. Some of my co-workers knew that we did this, and they thought my husband must've been rich (yeah, right, he was just out of school). They never noticed that we shared one car, I didn't have new clothes often, that I brought my lunch and sodas in a little cooler, and that I didn't go shopping every day at lunch for junk.
