I've been doing gig work for 3 years now.  It's been good. However tip baiting is at an all time high for companies like Spark/Walmart who do not hold customers accountable. Custer do not have to tip this is true. However to put a tip down just to get a ridiculous order filled and then take it away should have some consequences.  It's deceitful and it's a scam to put a tip in knowing from the start your not leaving anything.It needs to change it must change.
