Yes, rude. They’re saying your time is less valuable than theirs.
Not necessarily. Of course
some people are rude.
Some people are disorganised - and that's a form of rudeness too, when it impacts on others.
Some people as PP said, do struggle with the steps needed to be on time. I have struggled with being on time for ever. I used to drive my extremely punctual mother mad as a teenager. At university I was always running to a lecture.
I hate being late. I do a huge amount now to avoid it & most of the time manage it, but never with ease. I see other people instinctively & easily get ready, know they time they must complete certain tasks at, and leave.
I have to overdo my planning - for everything. Time for shower, drying hair, make up. I use Alexa to issue reminders to me as even if I've said that I need to be in the shower at 730, 730 will come & go without me being in the shower. The 'outside reminder' of Alexa seems to help.
Having kids has actually helped me. One in particular is really punctual. I do a huge amount to plan to be on time as I know how unfair it is to them if I'm late.
For work, I don't have a fixed start time, which helps; for meetings, I find once I'm in work, it's straight-forward to be on time for meetings but if it's an external meeting, all the same over-planning is needed.
I read a really good book a few years ago where there were case histories of people struggling with time management. I related to several. One of those was someone who tried to do too much before they left the house; I recognised that I did that. That was something I was able to stop.
This isn't an excuse I know, but for several years when I had 3 small DC, a full time job & no help (separated, useless ex) it really was horrendously hard to do everything. I'm some one who likes everything to be clean, tidy, organised so just walking out the door and leaving chaos was really hard.
And actually I'm a very organised person in most other ways, it feels like an anomaly.
Someone said to me, 'the only person you are stressing out is yourself'. This might not be true but it has stuck with me. I really hate the feeling of being late, the embarrassment & putting others out. I try to remember that & be really focused on being on time.
