The feat improves the record set by a Dutch barman by one hour.
Bart Van Opstal first came to prominence as a contestant in the first series of the Flemish "Big Brother".
The Fleming set to work on Thursday morning at 4 AM.
"On Friday, after 35 hours at work, I suffered a serious dip. I thought I wouldn't be able to keep it up, but I persisted and after a while it started to go better. My feet, my knees, my back and my hands all hurt, but I absolutely wanted to continue."
On Sunday night at 1 PM Bart finished his Herculean task: "I probably served for over 93 hours. I was allowed to take a 5 minute break every hour and that's something I didn't always do."
Within eight weeks the Fleming will know whether his record has been accepted by the Guinness Book of Records.
