#5:. Taste street food with no intention to buy
In some part of the country, street vendors will encourage you to have a taste of what they are selling, even if they know you may not end up buying.
Some people actually eat to their fill by tasting street food from numerous vendors. However, in Lagos, if you are going to taste it, you better be prepared to pay for a portion, even if it is as small as NGN50 worth. Most street vendors will reign insults and curses on you, while some other will take a step further and cause an embarrassing scene if you refuse to make a purchase.
