I live in Finland. In smaller venues up to 63A are common. 

In larger venues, like large Arenas and conference centers 
where lots of power need is expected it is common to see 
125A outlets. Larger sub distribution panels around 
the place giving you 125A ceeform and several smaller 
ceeform outlets (16A, 32A, 63A). 
For large systems you get power from several of those 
if one is not enough.  I have seen pretty many of those 
125A three phase outlets in use at Hartwall Arena 
(http://www.hartwall-areena.com/) in use to power 
the distribution panels that distributed power to around  
3000 computers around the arena during Assembly events 
(information and event pictrures at http://www.assembly.org/press/). 
Plus several 63A / 32A outlets around the hall for other show 
purposes (stage lighting, TV studio lights, several PA sets..).

Those 125A outlets are also seen in Messukeskus 
http://www.finnexpo.fi/ and places where TV production 
trucks are expected to park for live broadcasting...
