The president's Father's Day lunch yesterday was not hiccup-free, per ABC News:

Amid the bustle of President Barack Obama’s surprise stop for barbecue Wednesday, the White House apparently overlooked one key detail: the bill.

Celebrating Father’s Day early, the president had lunch with two service members and two local barbers at Kenny’s BBQ on Capitol Hill.

As the group chatted about fatherhood, the president enjoyed a steaming plate of pork ribs with hot sauce, collard greens, red beans and rice and cornbread.

The bill for the president and his four guests was $55.58, but was left unpaid at the point of sale, according to pool reports.

The White House corrected the oversight and settled up the tab by the end of the business day.
