How the hell do you forgot you have child in a car?
This situation aside, quite easily. Especially if not your own, you don’t drive kids places often, are exhausted or feeling unwell, have too much other stuff getting overwhelming, and of course the kid being nice and quiet. Possibly also just leaving the kid there for a short time at first, and then forgetting, which would be the irresponsible way under these conditions (heat, closed windows, no escape).
But who are you tipping, really.
In the US, there is such thing as “tipped minimum wage”. So, federal minimum wage is $7.25/hour, but the employer may pay as little as $2.13/hour themselves if the worker makes up the rest with tips.
Most extreme in Delaware. Minimum wage is $15/hour, but minimum tipped wage is just $2.23, so up to $12.77/hour in tips can just be a discount to the employer.
Why do you think tips are being pushed so much in the US? Chart per jurisdiction: https://www.dol.gov/agencies/whd/state/minimum-wage/tipped
