@AllieTheZone Another guy had me make a frappe, and then angrily asked me "is this the one for my dad" to which I said I have no way of knowing that, and then he made me make it all over again without whipped cream on top. Wasn't a dairy issue; there was dairy in the actual drink itself.
@AllieTheZone One lady lied and said she'd been waiting at the POS for 10 minutes even though it was more like 30 sec, and then made me stop what I was doing to look her in the eyes and swear to not do that again.
