The current scenario of Bangladesh is that life can come to a standstill and mobility at times can become extremely difficult. We are fortunate technology has advanced to such a level that we are offered many alternate solutions. 
We can conduct and continue with our lifestyle as much as is possible under the dire conditions!

Sitting at home you can conduct your banking/financial requirements by signing up and registering for online or internet banking with your bank. 

Many people are wary about the use of online banking, because they are worried about the security aspect. However, let me tell you that as long as you follow instructions you are safe.  Protect your password, do not share it with anyone, sign off as soon as you have completed your transaction and most importantly ensure that you do not conduct online transactions on a public computer and restrict it to your own laptop or desktop. 

Think of all the advantages that it provides you. Some of the many are:
You can check your balance and look at your statement for transactions that you have made.
You can transfer fund from one account to another account within your own bank.
You can transfer funds to accounts with other banks.
You can pay your credit card bills, mobile phone bills etc. using the online services.
Place requests for cheque books.
Request to 'stop payment' on a certain transaction.
There are many other facilities you can avail of and needless to say you need to complete forms and understand the methodology of online banking.
 I recommend that if you are not already using this service then please visit your bank manager and spend time with him to understand and avail of it. Trust me your life will be so much easier! 
The same can be done with your day-to-day requirements. You can make online purchases for groceries and food and receive the same without stepping out of your homes. 
For instance there are online grocery delivery companies through which you can order imported vegetables, cheese, meat etc. and local chemical free, fish, vegetables and fruits. Similarly you can go online and order food from various restaurants and the same will be delivered to your home and payment done after you have received it. 
Most of the above did not exist a decade ago in our country and today we have so many options and alternatives. Why not use them from the comfort of your homes!
