An unfortunate aspect of travelling in a poor country is that the notions of hygiene and cleanliness are far more basic here than in neighbouring countries, and even the hardiest of stomachs will eventually encounter an upset at some point during a stay in Bangladesh. Extra rice or bread might be served by hand; in most restaurants food is prepared ahead of time and left to stand for long periods, therefore eating earlier is better than eating later. These bouts of the ‘chitta shittas’ are often the topic of many conversations among resident expatriates and travellers, and you might be surprised at how frequently the topic of bowel movements is discussed, even at dinner tables.
Patience is your best tool in setting up a business in Bangladesh, as the young country has still to set up standardised procedures for many business transactions, or it operates according to laws that have scarcely changed since the time of partition. Furthermore, reliable business information and advice is hard to come by.
