With all this talk about soap vs beer while drinking in the shower, and worrying about getting suds in your drink and whatnot, I think it's important to point out that anybody who is worrying about their soap interacting with their beer or vice versca is doing this completely wrong. You should be drinking the beer while relaxing under the running water and coming down from an especially brutal bout of manual labor or sports-playing. If you are going to wash yourself, you do it AFTER you've drank the beer. I don't think anybody should be interrupting scrubbing themselves down to grab a sip of lager, which is insane and rightly ridiculed. I think if you're drinking a beer in the shower, you are doing it because you've busted your hump so hard that whatever you have to do next (in this case: shower), drinking a cold beer at your first opportunity is JOB #1. If you've got the energy to actually wash yourself with soap before you've even finished your refreshing, life-giving beer, you didn't need the beer bad enough to warrant drinking it in the shower.
And again, for the record, my opinion should be taken with the knowledge that I can't actually remember if I've done this before or not.
