This is a great pain in smaller shops that have lunchtime rushes.
Queue of 5-6 people. One customer nearer the front gets out their phone, locates the correct sub-app, scans, waits for confirmation, cashier gets confirmation.
This process, involving phone from pocket, unlocking screen, pressing screen, pressing screen again, scanning QR code for purchase, cashier getting confirmation, takes around 20 seconds (mainly latency on the physical interaction with phone part).
A cash transaction takes much less time.
There are 'bounce' apps that just mean you need to bounce against (hit) someone else 'bouncing', but they reduce the latency little.
Faster than card, but marginally.
/rant (stand in queues a lot)
And then scanning QR codes to add the shop as a 'friend' for a 1 Yuan discount (or demonstrate you've been a 'friend' before, more like a 0.2 Yuan discount). Wow. This can take over a minute.
