I don't think people outside the midwest understand just how ubiquitous "you guys" is here. After a previous time this discussion occurred on HN, I had to chuckle to myself when I heard my sister address a group of little girls as "you guys". It's our version of "y'all".
Even as far west as Colorado we used it the same way when I was young. Then I got a job at an NYC company and the gendered-ness of it was frowned upon. I actually switched to "ya'll" and it worked great. All the New Yorkers just thought that's how Coloradoans talk. So, thanks Texas.
Totally unrelated but this Blaze Foley song talks specifically about getting back to a place "where the people say ya'll." It's beautiful:
I am another Midwesterner who has largely switched from "you guys" to "y'all" (nit: ya'll is not considered correct spelling) after some lengthy and heated Slack discussions between Midwesterners and West Coast at $previousJob.
My first job was as a host at Red Lobster. I was reprimanded for saying "How are you guys doing today?" as I was seating a group of ladies. 16-year old me was trying my best to be polite, but language changes over time and that was one of my first introductions to code switching.
But this language has not been changing over time. This was a dictate from HR departments, made up from whole cloth. If anything has changed over time, it's that "gals" has been an anachronism for a long while, outside of a few isolated corners of the Southern and Western US where it can still manage to sound cute in some contexts. We don't really need a special diminutive for groups of women.
That being said, it's not formal language, it's chummy. If you're a 16 year old host at a restaurant speaking to a group of women older than you, you probably shouldn't be chummy.
I maintain that the sentence shows no disrespect to my Midwestern sensibilities. It's considered common courtesy to ask someone how their day is going, and I don't consider "you guys" to be a sign of disrespect. In fact, it seems quite clear to me that the parent was attempting to be warm and welcoming.
Warm and welcoming sure but too casual, you guys IMO implies familiarity, I wouldn't use it with strangers, could be regional or generational but that's my rural Illinoian take. Y'all is more flexible.
I agree with the other poster. Missourian and "y'all" is ridiculously less formal than "you guys". To me, "y'all" is specifically informal and is used in exactly that manner, even in corporate emails. It denotes a more conversational tone that's open to feedback. "You guys" does not exist within formal/informal for me, it's either, neither, or both, just depending on what you say around it.
"How are you guys doing today" spoken at a red lobster is absolutely fine, completely normal language, whether spoken by the president or by a child. It's the single most ubiquitous and wholly normal greeting that i know. Corporate really over does it sometimes
Fascinating - I'm from Michigan, and I would say "y'all" sounds more casual to my ears than "you guys." Formal speaking (in contrast to casual speaking) often eschews contractions.
That manner of social formality set sail a good 25 years ago my friend. On one hand I find it a shame, it was useful, on the other, it was also often misused (still exists in Korea where I now live, and it's abused like crazy here).
