When the bill arrives you already knew it was coming since you requested it. So you could have simply had your payment method ready. Then you look at the number and pay it. As adults do.
To make clear that you want to make the payment immediately in case this wasn't already obvious, one could use speech: I'd like to pay now.
That's the system.
In the exceptional and unlikely scenario where a waiter speeds away upon you wanting to pay, they aren't going to care about your green sticker system either.
If it takes forever for them to return, I drop cash on the table and leave. I'm not going to sit around for 20 mins and beg to collect my money.
