One I fell for: last minute, I needed to take a cat on a flight. I was googling what I needed to do for the airline and ended up with a scam number. The issue was I didn't even have to click through to the site, I'd like to think I'd have caught on. But the number was bolded in the suggested results without having to click through toanywhere. I was in a panic getting ready for the flight, so I wasn't on my game.
Immediately after I gave the person my credit card info over the phone, like literally the minute I hung up, I realized that it was so obviously a scam. Called my credit card company and had them block the charge and change the card number. Definitely not the pain in the ass I needed right before a trip, but it made me more cautious for the future and luckily I didn't lose any money.
My sister fell for one I couldn't believe. A kid was washing windows on the side of the road, she said she didn't have any cash and he said, "That's okay I have cash app, I'll type in my name." She handed her phone over and he cash apped himself $2000. No recourse since cash app isn't a real bank transfer. Expensive lesson to learn.
I feel like part of falling for this is being in a job where you don't question management doing stupid shit that shouldn't be your job. I works hope that $5000 would ping your bullshit meter, but I could easily see falling for a more believable story. Maybe not at a fast food place but like, a big office or some place where there are bullshit parties. Especially with a spoofed email or text rather than a voice call. "It's [some fake appreciation day] and I need to bring in cake/gifts, I don't have the business card on me, buy this $200 gift card and give me the info."
If you're stressed and have a shitty boss with no boundaries, I could see it working.
