Great biscuits!! Reminds me of Grandma's house!

There's an absolutely horrible manager who works early morning very rude and full of a bad attitude. Im nothing but polite i place my order and say thank you ( a sandwich and a drink)... Hes sighing on the headset tells me ugh. Well unfortunately its the only place with breakfast around here so i come back..whatever.. so i just want to know why hes rude every morning. I know some of us dont want to be at work but its how the world operates. Every time i see him i get bad customer service hes very rude. All the girls that work are great but its just dayshift. Oh and i want to add i just tried to get breakfast before an hour long drive and ive had to wait 15 minutes to get breakfast. The place is open 24/7 and it takes 15 minutes to cook biscuits.
