Have you considered using some more standard tags such as
brand=Walgreens
brand:wikidata=Q1591889
name=Walgreens

You could also add the website so users can easily access up to date information about this POI.
website=https://www.walgreens.com/locator/walgreens-935+andover+st-tewksbury-ma-01876/id=17588

Thanks for confirming my edit of closing Rite Aid.

I think you are jumping to assign malice.

I did use some code to help format the data from the website. This helps avoid a lot of human errors (and Wayland errors) when copy and pasting data.

Thanks, first party websites are indeed a valid source for OSM. The LWG have OKed it. To avoid this kind of confusion you can add a source on your changeset. iD walks you through this when you click "Save"

You don't seem to have provided a source. Where did you get the opening hours?

I created this changeset in JOSM. The data is from the locations.ikessandwich.com, eg https://locations.ikessandwich.com/az/avondale/514/.

You seem to have added an overlapping road+building way/225718668#map=19/33.344744/-96.584043

These roads aren't connected to the fuel station

way/1099953569#map=19/32.480115/-93.678269

You seem to have overlapping roads and building

way/754443719#map=19/31.585377/-84.217772

They don't come up regularly. I make changesets like this most days and only in DE is this discussion repeated. But yes, I should make an in-depth tutorial, I've thought about it several times. But it doesn't really interest me, and it takes time away from editing :) It's on my TODO list though.
