Do you have one piso?

Do you have one peso sir? five pesos? or do you have twenty five cents?

have you encounter this kind of problems with the cashier in a convenience store?
bus,or even in a mall?
This kind of thing is somewhat irritating, just like you have a 500 bucks on your pocket
and you do not what to ride in a bus paying that big amount to the bus conductor,and you decides to buy buy something in a
convenience store near buy and use that 500 bucks to pay what you purchase and the cashier would say a Maam do you five peso? or one peso?
you actually use that money to have a smaller bill. why does those companies or stores do not store a lot of coins?

I always encounter this when i buy and some cashiers are asking for smaller bill oh come on. did you you experienced this kind of thing also?
