I'm surprised at how prevalent the sign "We prefer MasterCard" is in Singapore.
Also, when I tried handing in my VISA at local 7-11, a staff there looked dissatisfied, by shouting out "VISA?!". This is not the only case, as the similar situation occurred just in a few days; every time when I tried handing in my VISA, the staff looked dissatisfied. This occurred at least 5 times in 5 days, which seems so many.
One staff at 7-11 even declined my VISA by saying "Ah, VISA...NO!". I asked why, and then he said the machine is broken.
My bet of him lying is 85%. But I paid it via EZ-Link.
With all these cases, they seem to like either cash or MasterCard, but I'm not sure.
So let me assume they do and ask a question.
Why does a local store in Singapore like to accept MasterCard so much? I wonder if the staff at counter receives some sort of charges, which depends on how a customer pays the money.
And is it rude to use VISA? I don't like to bother to ask them if I can use VISA; It's exactly the convenience that I love the card.
And finally, what is the purpose of showing "We prefer MasterCard", even if they accept VISA or AMEX too? This is not seen in other Asian countries, so I'm perplexed.
