A desperate cowboy rode his horse into a small town

A desperate cowboy rode his horse into a small town. His throat was parched, so he tied his horse to a pole next to a saloon and went in for a drink.
He came out a few minutes later, and someone had already stolen his horse.
The people of the town were looking to see his reaction, and they weren’t discreet about it. He looked around at everyone and said in a loud clear voice,

“I will walk back into that saloon to get myself another drink, and if I don’t see my horse right in front of me when I come out again, I will have to do what I did in Texas a year ago after someone stole my horse. And trust me, I didn’t like what I had to do in Texas a year ago.”
After his confident speech, the cowboy walked back into the saloon. The townsfolk looked at each other in fear and returned his horse.
The cowboy finished his second drink and walked out of the bar, saddled the horse. But just before he left, the bartender walked up to him and asked,
“Hey, cowboy, we know that we got you your horse back, but do you mind telling us what you had to do a year ago in Texas”
The cowboy looked at him with an iron gaze and responded:
“I had to walk home.”
