Lancelott:
You are misunderstanding him. He's right you know... an average hotel is only allowed five feet in Nigeria. but hotels have class.. as from 3 stars rating and above, you may go deeper but it has to be with a warning and life guard.
P S. the rules don't apply to club house pools, conference centre pools and tertiary institution's pools for sports

Thanks breh, I agree with you wholeheartedly. I guess my humble self has not been to an 'average' hotel in Nigeria, hence the misunderstanding. Cheers
