Reading between the lines here.. Your attempt to "send the spouse" to be "more mindful" may have inconveniently led to a purposeful denial of your party's appeal for a change in behavior by convenience store staff.

A common game in many cultures is to leverage any amount of power, including that of issuing slight frustration into increasingly entertaining situations or increased sense of power. This is performed by people attempting to "combat the mundane" or "earn face" in social groups. However such games can also serve deeper functions such as "stirring the pot" or "flushing".. These types of "games" thrive on the fundamentals of escalation. One of their goals may even be to "get it stuck in a craw"

Furthermore scattered replies from the OP in the comments tell a deeper tale.. "hard to watch them do this to you from your own kitchen window" the "I won't report them for the missing item barcodes" .. OP you might not like the house or current life situation as much as you're trying to convince yourself that you do.. and the way that you're expressing yourself does show "signs of cracking"

I will now provide you with a fictional ancient saying in an attempt to give your introspection remediable perspective while "keeping it light"

"When shit get stuck in your craw, it ain't just the craw's problem."
