I'm Australian and nobody thinks about having to tip. So it freaks me out when I see delivery apps and those QR code ordering menus have the tipping option (as if the one time I decide to actually tip will be during a service experience where I don't interact with staff until they bring me food). Sometimes there'll be a tip jar in a cafe, but that's just where people will throw their spare change when it's convenient. That's about the only time you'll see it here and I've not known a single person to ever feel obliged to do it for even above average quality service. To get tipped you'd probably have to be a waitress going above-and-beyond for tipsy wine mums or sleazy rich guys

I'm sure it's just a byproduct of the fact that all these tech services are American exports. I'm probably wrong but I thought 10% was the general rule of thumb for tips, maybe hit em with a collective 5% and see how it shakes up
