General Tips:
• Go around in two's or three's -- avoid being alone if you are not sure where you are.
• Dress modestly, i.e do not draw attention to yourself with your dress or your manners.
• Shops are open from 9-6 on weekdays, from 9-1 on Saturdays and most shops are closed on Sundays. Sorry, not much late-night shopping, other than at shopping malls.
• Follow your instincts, e.g. if a place looks like bad news, move on.
• Electricity 220V, 50Hz. Till 2007 power supply used to be regular. Since 2007 frequent power outages have become the norm.
