The hash of the witness program is then embedded in a P2SH script:

Now, Bob can display this address for customers to pay for their coffee. Alice's wallet can make a payment to +3deadbeef+, just as it would to any other bitcoin address. Even though Alice's wallet has no support for segwit, the payment it creates can be spent by Bob with a segwit transaction.

Now, Mohammed's clients can make payments to this address without any need to support segwit. Mohammed's company can then construct segwit transactions to spend these payments, taking advantage of segwit features including lower transaction fees.
