Well, the real questions should involve productivity.
If engineers start bringing their laptops to the Pub for lunch, what happens to design cycles? The extra hour gained with ability to perform circuit design during lunch should be a bit of a boost in productivity. However, at some point the consumption of beer will begin the negate that extra productivity.
Would all facets of electronic design be affected equally? For example, is it possible that circuit design would be negatively impacted but layout positively affected? Would analog design take a bigger hit than digital? Software more than hardware?
I suggest a detailed research program to characterize the effects of varying amount of beer on the set of electronics design sub-disciplines. Once the study is complete, an industry association could publish guidelines, perhaps in the form of a new ISO standard, recommending specific pub-based WiFi utilization time and accompanying beer consumption volumes for the maximum increase in productivity.
If you have a smart phone you don't need the wifi to send connect to the internet. I do think combining beer and wifi may lead to some "interesting" texts.
When I am traveling and need to go online with a laptop I will find a Starbuck's, but I am not meeting and interacting with people, I am working.
I would think that having internet access would change the pub experience greatly. I am not sure if for good or bad; consider here in the US the proliferation of coffee shops that provide free wifi and yet still make money and still have people meeting and interacting just like before.
