Good. If it is not reliable, it's a further harm than good if it exists as a false security.
An analogous example: my local pizza delivery (where I worked) would shut the box with a safety sticker, to avoid tampering / dipping by the delivery boys. Now, sometimes they would forget to do this for various logistical reasons. Every one of the non-stickered ones started getting returned as customers worried a pepperoni stolen. They stopped doing it shortly after.
This is actually kinda true with doordash etc. Those drivers are completely unvetted, they don't even have an interview.
The kind of people that can't get a job at a pizza place.
Personally, I never order delivery through these services. The incentives are all wrong. Not to mention the costs are super high: restaurants don't make any money, I pay out the @$$, and the drivers are given sub-minimum-wage pay after taking on the risks of delivery driving.
Eh, I'd consider that a failure of employee training and reverse the situation by giving out a weekly bonus to shifts that did not fail to put the security stickers on.
Kinda like if they forgot to put the security seal on your aspirin, I'm not going to take them all off because someone forgot to run production with all the bottles sealed.
The bottle of Aspirin goes through many hands between the manufacturer and you including sitting on an unattended shelf open to the public. The person making the pizza is working for the same company as the person delivering it, or may even be the same person. If you can't trust the pizza co delivery person then you probably shouldn't trust the person making it either.
