I'm in full agreement that as a general rule, there should never be any surprises when you buy something online. But complaining about the variation in packaging is over the top and unreasonable. I've been buying from Benelliparts since about 2014 or 15 with no disappointments and I've purchased at least one of every part he has ever offered for the M4.
You should know that in most cases, people are only reacting to how you treat them. Not only was your tone unfair from the first text, you asked him a ridiculous, almost comical question like "Do these two tubes look the same to you?"
Uh, yes. Yes they do....how else should he have responded? His reply was friendly in my opinion. You don't call people you truly dislike a big dummy.
And not that you ever should, but if you're going to make fun of someone's fluency in a language or writing ability, shouldn't yours be flawless...at least until you're done with that sentence? It's aren't, not arnt. Anything, not any thing. English is spelled with a capital E for Christ's sake. 85% of your sentences would fail a 9th grade English writing assignment. Be critical of anything else, but not English writing.
