I doubt very seriously the general user will get to upset if they did a search for a term and was delivered different results

The users I've talked to have been. It looks like G is using the same thinking you are and not realizing people are getting frustrated by it. When I say people I mean the random ones I talk to at the coffee shop some times. I mean random 'Joe Public' who has no idea why the results keep changing. Ask around a bit, not people you know or people who know about how search works, but the random people who have no idea... The answers might surprise you.
