Though most people who celebrated Thanksgiving in San Francisco had a lovely time (I did, didn't you?), not everyone was so lucky. At least two Thanksgiving Day meals in San Francisco ended in violence, police activity, and arrests.

It was 8 p.m. on the 400 block of Serrano Drive, which is in Park Merced when one of the altercations occurred. According to the San Francisco Police Department, a 28-year-old man and a 25-year old man engaged in a "family dispute...during dinner."

Suddenly, police say, the elder man interrupted the Thanksgiving feast, got up from the table, and "got a knife from the kitchen and stabbed" the younger man.

The knife wielding man fled on foot, police say, but patrol units later tracked him down and he was arrested. The injured man was transported to San Francisco General Hospital for treatment of his injuries, which police say are not life-threatening.

Less than an hour and a half later, a second celebration was interrupted, this time by a trigger-happy diner. In that case, police say they were called to the 700 block of Burrows Street, in the Portola, at 9:29.

When they arrived, they learned that a 30-year-old man pulled out a gun as he dined with two women, aged 22 and 43. The women, police say, "felt uncomfortable so [they] decided to leave." The man appeared to take offense at this, and pointed the gun at them before firing it into the air, according to the SFPD.

He then fled the scene, police say, but was later taken into custody and booked under suspicion of "Negligent Discharge of a Firearm." According to the SFPD, no one was injured in the gunfire.
