What would you say to them? How will they benefit from accepting Bitcoin as a payment method?
i have done this a few times with success, learnt many things and here is my advice:
firstly you need to find out how many people that already know/have bitcoin would actually use the restaurant..
for instance if it is just 1 person a month, then its not really in the restaurants interest to waste time teaching all their staff..
as such dont tailor your salespitch to be something common that all the staff should know off by heart..
next is to think about how the restaurant will process the transaction.
again if its one customer a month then getting the restaurant to sign up to bitpay or coinbase will again NOT be something worthwhile.
for those small transactions per month the best success is to set up a bartab (pre-pay) the restaurant $50 and give them a leaflet to show how they can check
the value of the meal, and then request that value of bitcoin to a QR code owned by you. and check the funds were received.
with it being a leaflet it can easily explain it without training and also have the QR code printed on it ready to show customers
that way the bitcoins go to you and the restaurant can just take the cash out of the tab and put it into their cash register.
tell the manager that he loses nothing and you will do all you can to increase their customer base. and if he could put a 'we accept bitcoins' logo in the window.
..
now if there are more then a few customers a week then design the leaflet/salespitch to explain how to process a payment via bitpay /coinbase (if you cannot handle the bar-tab yourself)
you may even want to organise a bitcoin meetup, and use the time to have a live demonstration of processing a bitcoin transaction.
next you will have to think about the way you talk to the manager. so find out what payment methods they accept. find out if they are linked to those food ordering websites.
now that was things to think about before even talking to the manager.
now with all of the information about how popular bitcoin is in your area and how much the manager already wants to accept many different payment methods will help you work out how easy or hard it will to tell the manager about bitcoin.
the best way to talk to the manager is not to use techy speech. for instance watch a few apple pay adverts, watch a few amazon adverts and keep it as low-key as that. make the conversation about how easy it is to accept a transaction (handing the customer a leaflet with a QR code on it) and how easy the manager will receive the converted fiat afterwards. aswell as how little the manager has to implement it and how little training it will need to implement. aswell as no costs to the restaurant.
DO NOT USE THE WORDS: decentralized crytographically secured ledger..
shop owners do not care about the technology behind bank wire transfers, or applepay algorithms. all they care about is ease of use and getting paid.
so concentrate on that.
very well said and nicely replyed , i totally believe your reply, it also can be done like in my country meals voucher are given my corporates to their staff , they exchange that voucher value to the resturant and have their food, the restaurant owner claim that voucher from the voucher company . so like this process can workout with bitcoin. like issuing bitcoin voucher. but the only problem is fluctuations of rates. then the voucher value cannot be changed. we have to work on that value fluctuatiing issue.
