I used to use my phone to help guests when I didn't have access to a My Device but once I went full time on SD I had the right equipment. Zebras are great for helping guests if you can get one.
We were told NOT to use our phones for guests to get Cartwheel discounts. We were allowed to use Zebras if the guest didn't have a smart phone. If they did, we were instructed to show them how to download the app. When they put Cartwheel right into the Target app, it worked for a while when you were logged in as Target but once Wallet was introduced, youhad to have an account to use Cartwheel.
Bam! No more free Cartwheel for flip phone users and computer losers (j/k about the loser part)
One GSA always told me to use my phone. Like, no it's against policy and I don't want my "just for you" section full of Dr Pepper and diapers. I manually offered the discount to a handful of guests who did not own computers or cell phones, not even flip phones. We're talking one luddite and 3 or 4 ancient oldsters. K1 - arrow down - type in percent - K3. Easy. (God, by the time I go back to work in another Target, I'll have forgotten all the functions)
Before we closed there was that 20% off clearance clothing offer. My opening cashier called me over to say that the guest (mid 30's with an iPhone) was having trouble with her Cartwheel. I explained that it was in the Target app now, and if she opened it, I'd show her where it was.
The guest said "I don't have an app" so I said, "no problem, let's get you started saving money".
You'd have thought I suggested she start taking off her top right there. Got so pissed and refused to load a free app onto her phone. One of those "you shouldn't have to do that, you should let everyone get the discount!".
So my cashier says, isn't there a way to do it on the register? I'm like, not really, only if Cartwheel scans but doesn't pick up an offer they added. We can't go changing prices willy nilly since the technology is available.
The guest said, well never mind, I'm not putting your app on my phone so I said, okay, well, if you change your mind, let us know.
The next thing ya' know, the cashier is changing the price on EVERYTHING. I called my GSA over but she was like, fuck it, we're closing, I'm not doing anything. (This one literally just stopped working a month before close, just stood around)
I don't know why but it aggravated the crap out of me, the cashier willfully breaking policy and the GSA being a useless lump but I was seriously aggravated that day.
Of course, in the big picture of things, our store is closed and who gives a fuck. But for all the stores that are still open, policy is important and you should use your phone if you can't access a Zebra to help guests but not to give them Cartwheel.
TL;DR
words, cartwheel, don't use your phone, people suck.
