The manner of issuing a cheque justifies your sincerity...

In our country is a practice to issue post dated cheques in most business transactions. 

For example, a 30 or 60 days term bill is due and the shopkeeper has to make payment for it. A good boss might issue a current cheque to settle the bill immediately but a more smarter boss would issue a post dated cheque for another week or month. To the smart boss, he has considered that payment is made though cash hasn't be transferred yet. The delay of the post payment allows the business man to roll over his stocks and sales. Smart ah? However if you happened to meet another smart and cunning boss, the post dated cheques are always post dated on a Friday. Friday looks like a week day but it would take another 2 working days before the transfer is realised. So the receiver has to wait until next Tuesday to utilise the cash. 

In business is bearable to receive post dated cheques, for at least you have a cheque to hold your customers.   To me, when a friend is borrowing from you and he issues his personal cheque to honour his debts. Please look at the date he writes on them. From Monday to Thursday is considered as sincere that your friend is willing to repay his borrowing. But if the date is a Friday or the day is the eve of a holiday, it indicates that he still not willing to pay. Merely he just wants to delay further of his debts. It took me years to realise the behaviour of cheque issuing.
