Amstel Light is an extremely common and perfectly respectable choice for the mid-ranking employees of my clients and partners when I take them out to a bar. (Senior decision makers generally get a dinner where it's wine and scotch all round.) Natty light, PBR and Keystone are not acceptable and will lead to comments, raised eyebrows and a sense that you don't quite belong.
Edit: It is, of course, all about branding and not a bit about the beer. Amstel has made themselves 'premium'; PBR did the opposite. If you're a connoisseur, as your profile says, then you can avoid the issue altogether by ordering a good craft beer. That's still keeping it classy. You'll just need to exercise more.
Nobody is saying you have to drink light beer, just that if you're going to drink light beer, pick one that isn't associated with daytime drinking rednecks and frat houses.
ahem, in all seriousness, in my part of the world Drinking is a huge part of the working and business culture. Does that apply in the US too? I work with some partners who pride themselves on getting you the most drunk they can
I'd imagine positions that require a lot of networking and personal contacts (sales, Executive positions) would have more of this than your regular Joe grunt programmer.
