Do you also have venues using odd or misusing connectors in an attempt to force you to buy power from them?
Buy power? No. We just turn up and plug in.
In the US you seem to have a lot of connectors to choose from. Over here, it is very standardised. Domestically, you will only find one type of outlet, the 13A socket, unless it is in a house which hasn't been upgraded in the last sixty years. And in commercial and entertainment venues, you will always find the outlet I showed above. These come in 32A, 63A (why not 64?) and 125A versions.
So yes, I think the siuation is better here. Not in a smug "we're better than you" way but because you are in a bigger country which has had a lot more standards with regards to power connections over the years and your country tends to work with rules issued state by state whereas ours affect the country as a whole.
Standards of maintenance and attitudes to its importance are more to do with human nature than anything else and I'm sure we have our fair share of people whose standards are not good enough.
