all depends.
take for instance my last two trips to Lonestar Steakhouse. from me its id say a 30-40 minute drive.
my earlier trip, got a waitress that was slow to come get an order, refilled drinks pretty much only when we were about to leave, and checked back with us once throughout our 1.5hr stay. we ordered ~$50 in food. (me and my girlfriend) for her shitty service, she got $1 just because thats the smallest thing i had on me although i should have left her nothing.
my latest trip, got a waiter that was over within the 1st 30 seconds of us sitting down ready to take our order, we ordered ~$75 in food that night. (me and my girlfriend) service was exceptional, food was perfect, and he was there right when we needed a refill, didnt even have to ask. while we were there i saw the waitress we had prior talk to him and look over at us with a ****ed up glare, i know what she told him. the service didnt change. he went home with a 100% tip that night, and the earlier waitress was mad as ****.
worth the extra money, id say. i was laughing my *** off... too bad she didnt come by and say something, that would have made my night //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
