<human>: I was at a Best Buy purchasing a new wireless router to replace one that finally died. As I was looking at the available routers, an older man (guessing late 60s) was also looking to purchase a wireless router. The best buy employee immediately steered him to a $200 model, and told the older man it was much better. When he asked why, the employee said "This one is IPv6 ready. The internet is running out of addresses, and will run out by November. When that happens, routers not IPv6 ready won't work anymore, so you need one that is." 

I'm sure many of you can figure out the multitude of things incorrect about that statement... my question is, should I have intervened, knowing a decent amount about technology, saving this poor guy from being ripped off? Or is it not my place? I have been in this situation before and have intervened, and neither party was happy about it, which is why I did not do so this time... but I felt really bad, especially because he was older. What say you reddit? Also, if it matters, The older man ultimately purchased this expensive but recommended wireless router.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: An older guy was getting ripped off at Best Buy, and I want to know if I should have stepped in or if that is considered bad form.
