Question About Designer Testers at the Mall

Does anyone else think the testers they got at stores like Macys, Sephora, etc. are watered down? I've sprayed stuff recently on my wrists when sampling or shopping around, notably trying Dior Homme (Sephora, disappeared fast, compared to the 2006 one I got which lasts me a workday easily, very watery and barely even noticeable opening, we're talking seconds after spraying, wtf); L'Homme (Sephora, lasts literary less than an hour on my wrist, I mean I know it's not a powerhouse but it shouldn't disappear that fast); Bleu de Chanel (Macys, so I sprayed right before I went to watch a movie at the mall, and it only remained on my skin for like 3 hours).
These are supposed to be authentic bottles, yet they lasted less or were less noticeable than frankly many samples I've had (vials we're talking bout). We're not talking projection here, talking digging my nose in my skin. It's not exactly a recent observation for me, I've always had that impression of these testers. I doubt it's olfactory fatigue since I didn't spray all over with numerous different ones. More of a one at a time testing sort of thing. Anyone else think the juices they got at the Mall are very watered down (most of my stuff I've bought online and I find it generally stronger and longer lasting that what I sampled at the mall pretty much for every single cologne I've owned and previously tested), and if so do you know why?

to be fair I am assuming since you are a woman, these were mostly female frags? Generally female frags are way more bombastic than male frags, sooo I guess I should have specified in my OP, primarily male oriented frags

i'm basing this on the fact a lot of the best selling male offerings you see at the mall are things like Burberry London, Versace Fresh, Chanel Allure Homme Sport, Dolce & Gabbana The One, Dior Homme, Acqua di Gio, Gucci PH 2, L'Homme, Bulgari Aqua, etc. which are generally not very powerful frags (a lot of fresher scents, obvs don't last long). Le Male, 1 Million, A*Men I think are exceptions to the rule. Comparably, I've hit up some of the notorious female frags and sprayed on my skin and they've lasted longer (J'ador, Mademoislle, Flowerbomb, Black Orchid, Poison, etc.). Female version of scents like Acqua di Gio and Code also lasted a while when i tested them a while back, and clearly that's not the case for me with their male counterparts. I also think the female Angel is much stronger than A*Men. Granted, I think those were EDPs, but yes I do think the female stuff "generally" tends to be more prominent on potency. I think the male scents are marketed to be more subtle, less "perfumy." Not to mention fresher scents are hip in the men's game, and fresher scents are lighter.

Now if we go into the niche realm, or some tougher to find stuff we get some bombastic male or unisex frags, but I was referring to the stuff at the mall, like Macys or Sephora. No Montales, Tom Ford Private Blends, Amouages, etc.

In regards to my op, maybe it could be the light or something. I mean yeah, those things do get exposed to light constantly and who knows for how long. According to general consensus on light and frags, that should be damaging the juice. From personal experience I haven't noticed particular damage on some of my older bottles that have gone trough hell and back (light and heat in the bathroom) but IDK could be it.

No but i have a frag there for a few years.

Man this is the kind of the thing if someone was applying for a job there could say at the job interview to strengthen their case for the job. Nice.

I think it's a combo of light exposure and also old frags (the L'Homme one I tried was maybe 30% remaining)
