I'd encourage use of StreetComplete, you can walk around your local area and get lots of points to survey with data on street widths or businesses' opening times. Imagine if all the people who were busy with Pokemon Go used that, OpenStreetMap would be nigh perfect in terms of data.
Amusingly, it's widely believed that improving location information is a big part of the reason Niantic (at the time a subsidiary of Google) created Ingress (their game before Pokemon Go—and a much better-designed game, IMO) in the first place.
I just recently put in a Note for a fix in my local area (not a business, but an incorrectly placed toll road), but looking around the area I see a bunch of other Notes that are months old that don't seem to have been actioned. So I don't have a lot of hope that my feedback will be fixed any time soon.
From what I could tell, not without creating an account. And because this is something relatively unusual (not as simple as changing a business's opening hours or something like that), I'm not even sure I'd be able to figure out how to do it in a reasonable amount of time. I'm not willing to put in the effort to do all that before I've ever gotten value from the app (since this was a problem I noticed the first time I ever tried actually navigating anywhere).
Can you link your note here? I might look over the area and do some of the notes. There probably isn't any mappers ever looking at the area if there's a bunch of really old notes.
You can download an app called StreetComplete that makes it very easy to do little edits such as marking whether a bus stop has a bench and what material the sidewalk is made of. It's also available on FDroid!
