What will be your decision as Sales Person if an important customer during Call gives you an Option to take Small Order right now or Big order later?

I will go for that 

from my experinces , every company starts its sales by small operations which by sequence later will lead to the big one and for any customer when you make sales i have my own concept (( Take it know Or you will loose it )) as you never know what happens the day next ,may be the war start .

, then you will not add the big to your company nor the small as well.
