If you cannot accept their practices then go back to Bangladesh where you can spend the whole Friday to malling or park socializing. The best thing you can do is to respect their laws, mores, and practices as to their culture is shaped. Remember that you are just an expatriate there and you have not any single right to demoralized or de-culturized theirs and every people's culture. RESPECT IF YOU WANT TO BE RESPECTED. No hard feelings. Good luck.
