At diners and restaurants ketchup is left out. Even ketchup packets and dispensers.
yeah, cuz it won't spoil like other condiments. no reason to keep it in the fridge
No this is completely inaccurate and silly. Restuarants go through gallons of condiments daily. The reason they sit out on the table is because they are used throughout the duration of business hours. Therefore the new shyt they fill up the bottles with is unopened.
Ketchup packets dont need to be refrigerated because they aren't opened. Obviously.
At the end of the night or shift, ketchup and mustard bottles must be put in fridges. Any steakhouse or burger joint youve been going to that lets them shyts sit on the table overnight for the next days business is violating health code.
Its common to pour new ketchup in to old ketchup bottles...like I said the old ketchup that has been sitting out for 6 hours is still fine to eat and you just pour new ketchup on top to full the bottle. Either way all the shyt is getting eaten or wasted and thrown away during the duration of business hours.
Most businesses either have a big as can of ketchup like this
or
that they get in bulk
and use to refill. or some have dispensers which have bags filled with the condiment that they use to squirt into bottles to refill them the oxygen never hits the condiment inside the dispenser so technically that can sit out for months or weeks until empty like this
or these
