There's big debate out there on tipping grocery drivers apparently. On one hand, they are getting $5-7 a run and get 65.5¢ per mile on their taxes for the gas, wear and tear on the vehicle. On the other hand, it can take an hour round trip to pick up and make a delivery depending on the delay at the store, loading, traffic, etc.. There must be a reason these folks are driving for money. McDonald's pays $14 dollars an hour here and other places are paying more, so driving must be worthwhile or at least better than schlepping in a restaurant or the Home Depot.
For me its a quandary. On one hand, I'm a decent tipper in general; on the other hand, I only bought the service to try for half price! If I'm paying $2-5 for a tip every time, that can add up if I use the service a lot. That's why it ticks me off that I cant have certain non-perishable items shipped if they have it in the store. I would rather use the shipping for that stuff and not deal with a driver at all, then go to the store for stuff we are nitpicky about, like produce.
Something I DID read is one person who was a driver for several services says either tip in cash or after the fact because the vendor, Walmart in this case, will not raise the competition delivery rate for drivers, using the tip you already added as an incentive. Apparently, the way it works is, Walmart starts offering the delivery to drivers at $3 and if no one takes it, it starts bumping up during the first hour and can reach $8 in an hour if no driver has claimed the job.
With Walmart you have 14 days to add a tip if paying with a card, I think is what I read, so you can see how your delivery goes, then come back and tip. But, the thing is, what is there to complain about with a delivery other than maybe time frame? If the store picks and packs everything, it's not the driver's fault if the store got something wrong or caused a delay.
On the scan and go. I need to hold my wife's hand on that. She does most of the Walmart shopping but is a bit of a Luddite regarding new tech stuff like that. She still waits in line for a cashier while I will used self-checkout even if I have many items. I prefer to pack my own bags.
I love scan and go at Sam's and we keep storage stuff in the back of our van to hold the stuff till we get home. I dont like the "theater of security" to get out of the store though. I should not have to wait in any line after I have paid. And the security is not all-that. I accidentally got out of there with a $60 jug of peanut oil without paying. When I called to tell them this and apologize, they had no easy remedy. I was ready to give them a credit card and they said the only way to do it was to bring it back and ring it up. That's a 35 minute one way trip and at least $6-7 in gas. They just accepted the loss and thanked me for my honestly and caring.
