In the city with the fourth gym leader, around the building when you walk in on that same road, is a kid who burned his tongue on some hot tea. Either he or his grandma inside the building gives you some, and you bring it to the guard, who in return, lets you go into the city with the fifth gym leader.
first you go to the town to the right where the grass gyme is and ask the old lady in one of the buildings near the pokemon center then she will give you tea and you take the tea to the guard
Lemonade can be bought at a vending machine in the department store.
You need to get around to Celadon (via Lavender Town), visit the Pokemon Mansion there and an old lady will give you a hot drink, take it to the guard and he will pass it round.
he doesn't do anything. he just whines that he's thirsty!
When its tired. LOLOLOOLOLLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOLOOOOOOLLLLLLOLOLOLOLOLOLOLOLOLLLOLLOLLOLOLLOLOLOLOLOLOLOOLOLOLOLOLOLOLOLOOOOOOOOOL!!!!!!!!!!!!!!!!!!!!!!!!! ZOMFG OWNED!!!!!!!!!!!!!!!!!!!!! LULULULULULULULULULULULULULULULZZZZZZ!!!!!!!!!!!!!!

You can move the thirsty guard out of the way by giving them a drink of water or redirecting their attention elsewhere. Alternatively, you could try to find a way to distract or incapacitate the guard temporarily so you can pass without issue.

The thirsty man is at the gate between Canalave city and route 218
At the top of Celdon city , well there is a building there and right at the last floor you can go to some vending machines and buy water and give it to them
You can not give anything to the policeman who says he's thirsty to drink on Route 218. This is a reference to guards who said the same thing in Pokémon Red and Blue.
Go to Celadon City and buy a drink for the guard and he will let you through
The thirsty policeman on Pokemon platinum unfortunately can not be satisfied, and any item you have will not work, this was not created for a reason although it might have been before but been dropped by the makers. Sorry. He will remain thirsty forever... :)
