you can write things down, on paper, a note, send someone to the store, and they will still come home with the wrong item.
Mom needs a lot of light for her quilting and we've had these large bright shop lights in her room that shine light up on the white ceiling and that reflects down all over and she could see well enough, until the day before yesterday one of the lights was flickering so i got up there and checked it out and yes, it was failing, so time to replace it.
item wanted, shop light, plug in, no plastic diffuser cover wanted. the person who helped Mom gave her two lights, direct wire, diffuser cover, arg! it wasn't going to be enough light. so i had to run out after she got home last night and get the lights i needed or she'd have not been able to quilt this morning.
oh, did i mention the helper gave her lights that were more money for less light and not very efficient? lumens, color/temperature and efficiency are important. so pretty much for $12 extra i doubled the light and improved the energy use and got the right temperature.
the shopping experience itself was horrible, they had this loud obnoxious music playing on repeat in that section (like it was wired right into the display so i couldn't ignore it). if there's anything that makes me want to walk out of any store it is annoying piped in loud music.
another annoying thing was that some boxed items were not clearly marked as to whether they were direct wired or had a plug. one rather nice unit i would have bought i had to open the box to find out if it had a plug or was direct wired. sadly it was direct wired and i wasn't going there for this project...
i hate shopping... *grumble, get off my lawn, etc.*
the drive home was right at dark and it had rained today and there was fog all over so i was wary of deer running out. as i was coming down our road (the final stretch) there was a deer standing right at the side of the road like it was planning on coming across but i saw it and slowed down enough and it didn't panic and jump out in front of me at the last moment and also it didn't run into the side of the car (which has happened to me before) so i did get back home safely.
the light worked and are doing their job and Mom is fine today.

keeping Mom happy is my job as much as possible...
p.s. the LED shop light lasted 10yrs. we have five more of those that haven't failed yet...
