My first tech job was with a place that did net security mostly marketed to fast food places. Some of the evening shift calls had me questioning reality since most of the people I talked to where fry cooks first, shift managers second, and by default of seniority the tech for a site as needed.

Countless 'the computer won't turn on' calls which ended up being them pushing the power on the monitor.

The one that called up just to listen to our hold music until I answered, which was actually pretty good, sort of an industrial/techno thing.

CS: The system just crashed, can I turn it back on? Me: Sure go ahead and let me know if there are any errors. CS: Hold on I can't see the button, the power is still out...

CS: Our internet is being really flakey. Me: What lights are on at the gateway? CS: It's hard to tell, it's underneeth the pop machine, by the way the pop won't stop spraying, how do I fix that?

And the one who got so frustrated with trying to fix things they hucked the firewall/gateway into the deepfryer and asked for a RMA.
