I have personally never, ever been to a restaurant where the server didn't have easy access to change. I've traveled quite a bit over a good number of countries and eat out often.
I'm not calling you a liar, just saying that you do seem to have very limited experience to a certain kind of serving, so I'm not sure the "but it's so hard for servers to get change" excuse flies either. Even if it's more difficult for that server to get change, that's no excuse for a server not to bring change to the person waiting for it.
i've lived in and traveled through a lot of places, everywhere has had a till and i've been brought all of my change
Count me in this group. I go out to eat at least once a week every week and have for almost 20 years consistently. I live in NYC but regularly travel throughout New England, NJ, Penn, and have frequented FL, LA, CA, NV, and Canada and have been to Japan and the mid-west plus various countries in Europe half a dozen times. The norm in all these places has always been all my change. Yes occasionally pennies are rounded to the nearest nickle, as is the official way in Canada, but over 4 cents, I have consistently always gotten all my change unless I indicated I didn't want it ("no change" or "keep the change" etc).
This rounding to quarters, half dollars or whole dollars might very well go on in a few select places by a few select waitpeople, but it is a far cry from standard anywhere I have ever been. And this goes for hole in the wall greasy spoons in shifty neighborhoods to high end, rubbing elbows with the 1% in places like the Hamptons - change is given in total as standard practice IME.
