POOR SERVICE AND RUDE WAITER PLUS MANAGER

My Husband went to the restaurant and asked the waiter to prepare a meal for him , he'll come back after 20 minutes then waiter told him "that's not allowed, he'll have to wait for it and leave with it" he then asked him what time are they closing? he said 10PM my husband left & came back at 9pm the restaurant stuff was already packing & cleaning he asked waiter where's his food? "The waiter told him they didn't prepare it cause the restaurant closes early when they are not that busy especially on Mondays " so they had an altercation until the restaurant manager intervened ,he told my Husband that the waiter mislead him , in hopes that the manager will make a plan for my husband guess WHAT? the very same manager ended up siding with his waiter ..what kind of a service do you guys run? This is nonsense you don't treat customers like that😡what management qualifications does he have for such POOR SERVICE? I am so disappointed and actually disgusted
