Here in the Philippines Bitcoins name is so popular because I think Philippines is almost top of users of social media using computer and cellphones, so about the store to accept bitcoin is not yet as of now because our number one Big Store here in the Philippines is not yet involve of Bitcoin how much more in a any other small stores. so ASKING is not necessarily as of now I don't know after several months or years. If ever our government here is not recognized bitcoin anymore, all big store are no longer to accept bitcoin because all transaction has been made are with OFFICIAL RECEIPT.  

I dare not ask that in my country as no store allows it. I might be able to strike such a deal by talking to owner privately but I do not have time for that.

This is indeed a very great idea. This will probably boost the popularity of bitcoin, because more and more people.will hear about the bitcoin, or somewhat others may feel the courage to asked at the same time they will feel the curiosity and do some research. In this way we can encourage more people to lovw bitcoin.

We can ask the stores if they are accepting bitcoin. Or the store shoul put a signage that they are acceptinh bitcoin as payment just like the strategy of different credif cards there are signage that indicates that the stores accept cards as payment.

I think that is unnecessary to ask.
Because we all know that when you are in bitcoin industry. You must know all the stores or establishments who are accepting bitcoins.

In USA overstock, dish, microsoft (limited), paypal, newegg, expedia, shopify.

Not many yet due to extreme btc volatility. We need to stabilize cryptos for this. there are various schemes, but nothing dominates yet.

a store may receive a bitcoin payment after getting government approval, if it's only from a group of people I do not think that's possible

it depends upon the store owner if he/she knew about btc.if you think its the right time to sell your btc for the goods much better especially in low price.the store owner will be benefited.

I never mean to pay by BTC at any stores, as the fee is high, and the process may not be simple I think.
It's better to just use BTC for investment, trading and holding.

And we can advertise BTC in another efficient ways !

There are countries where the store receives bitcoin. for use on fees and other use for payment. but there is still a bitcoin that can not be paid.
