Now I know you’re all curious about this place and you want to enjoy yourselves. That’s OK. I don’t want to spoil your fun, and it’s my duty to tell how to avoid putting yourselves and your property at risk. For all the girls here, if you’re in the bar or disco then make very sure that your handbag or purse is where you can keep an eye on it. Not on the floor or on another chair. If you want to dance, ask a friend to take care of it or take it with you.
    Um, for the gentlemen; don’t walk around with your wallet stuck in the back pocket of your trousers. It’s easy meat for a pick-pocket, believe me. As you are all foreigners here, don’t carry a lot of cash with you and the same goes for passports, identity cards and other important documents. For your own personal security, it’s always better to go home by bus or taxi if it’s late. If you have to walk home late at night go with some friends. If you’re alone, stick to well-lit areas. Should you see a group of people looking for trouble, cross over the road and, if you really think someone is going to bother you, bang on the door of the nearest house and ask for help. Oh, another word of warning: Don’t hitch lifts. It’s asking for trouble. If a car stops to ask for information, just keep well clear of the door so you can see what the people want. This isn’t a dangerous town if you’re sensible.
    To close, I just want to say that in this country it is illegal to carry a knife, spray or anything that can be used as a weapon, even if it’s for self-defense.
