If you really aren't interested, then be very clear and tell him politely but firmly (the hints that might work back home, won't work here).
The Spanish have a reputation as romantic and passionate people.
In France, Germany and Belgium, it's common for the man to ask a woman out, but in Switzerland, the men can be a little reserved so women might want to give them a nudge.
For French men, it's all about the chase, and playing ‘hard to get' is part of the game.
So what you say may be taken at face value – and you shouldn't always take to heart what's said to you. In the UK, drinking a vast amount of alcohol can be central in beginning a sexual relationship with someone.
If you're interested in someone, maintain eye contact – if you aren't, don't.
If you say ‘no' to an invitation, he may well think you're playing hard to get and will probably persist.
In the US and other English-speaking countries, the kiss just doesn't have the same significance it does elsewhere.
For example, in the UK, a woman might kiss one or more men when she's out in a club or bar (or vice versa) but it wouldn't necessarily mean anything or lead to a relationship of any kind.
