It was just a Long Island ice tea.
Road coke.
I had a teacher in HS in NYC (one of the “special high schools, at that) who had a vodka bottle in her desk drawer and used to swig away between classes. Kids could get extra credit for doing things like being messengers from the main office to the classrooms, and I remember coming in as she was hastily stuffing the vodka bottle into the desk drawer.
Prayers for her. She was an unhappy woman, but a good teacher. The vodka didn’t seem to interfere with her knowledge of Shakespeare.
On the other hand, she wasn’t a driver, so she wasn’t risking our lives...this driver needs to be canned.
Sometimes it’s the only way to cope for bus drivers; blame the students.
