Question about upcoming fork

[Peter789]

If a fork occures, then how will affect the consumer?
I mean will every peice of btc software have two pathways to send your btc?

For example, a Japanese person goes to purchase an item at the shop. Will the shop say ' send the btc via segwit'?

Will my ledgar wallet, once upgraded, have two paths to send btc along?

How will this fork affect the logistics of btc transfere? Is every btc wallet  going to have to upgrade?

Would you good people who understand this, please inform us, non techy poeple?

Thanks Peter

- there is no upcoming fork.

- if a fork occurs it depends on how it is done.
1. if it is like the last hard fork of bitcoin, with consensus and with overwhelming majority wanting that fork, it will happen smoothly and the "consumer" has nothing to worry about.
2. if it happens any differently with no consensus, and we end up splitting and having 2 chains then things get tricky. because again many different things can happen.
2.1. the other chain can be attacked, miners give up and move to the new one, nobody uses one of the chains, the price drops, .... final result would be a singular chain.
2.2. we have 2 working chains, same coins on both chains and wallet developers will find a way to give the "consumer" some way of user friendly deciding what to do, and you don't need to worry about it right now.
for example this is the statement Electrum developer made: http://docs.electrum.org/en/latest/hardfork.html
