I don’t think Neil thought for a second that thank you, you were amazing would hurt Andrew. And tbh I don’t think Neil would have even went through with their “this” if he knew Andrew actually cared. Neil was pretty convinced Andrew didn’t give a fuck and still wouldn’t when he died. So when he tells him thank you he still probably thinks Andrew isn’t going to care. But it’s something he needs to say and get off his chest before he dies. Like these are his literal last words. He couldn’t leave without thanking Andrew for making the last couple months the best he has had in his entire life. He doesn’t think that Andrew will even catch on to the significance of it nonetheless care because Andrew has told him this is nothing and Neil is quite possibly the most oblivious character I’ve ever seen in fiction so of course he believes it.
At my store, probably like most, we periodically have to do refresher training courses. Courses for stuff like safety, alcohol and tobacco IDing, fraud prevention, etc. Management puts this off until the last possible moment so in the week or two leading up to all the training expiring they rush to get us all up to date. This year, the managers couldn't get the training website to work for DAYS. The issue? A popup blocker. These managers are being paid 50k+ a year and are computer illiterate.
