Cause you'll be drunk.
Although we advise you to have a night so rad you may or may not end up remembering it, we do not advise you to have tequila accompany you on this fine hour* of immense strength. Maybe as a auxilliary drink, but were not here to send you to the hospital.
We are here though, to send you to someone's couch that may or may not elicit the phrase "how the hell did I get here?"
