tipping not sticking

[Unregistered]

if you tap on someone in the newsfeed, go to their bakery, tap three tables to tip, wait till it registers then hit the home button, when you go back to the same bakery the tips don't show and you have to tap again then it will stick. this also happens in empire. I don't always want to leave a message for that person, just clean/tip and leave, but I do want to know that they get the points.
Glitch? Thanks!

If you return to the same restaurant immediately, it will appear as though your tips did not "stick". They have though. Next time you see this, leave the bakery without trying to re-tip. Come back again and you will see that you no longer have any available tips to leave that player.
