how to chain methods using an object literal (always return this)

gistfile1.js

var myBooze = {
  booze:['wine', 'beer', 'liquor'],
	chosenBooze:[],
	getBooze: function (type) {
		var booze_length = this.booze.length
		for (i=0; i < booze_length; i++) {
			if (type === this.booze[i]) {
				this.chosenBooze.push(this.booze[i]);
				return this
			} else {
				return false;
			}
		}
	},
	consumption_style: function () {
			var consumption;
			var liquor = this.chosenBooze[0];
			if (liquor === 'wine') {
				return "i got class"
			}
	}
}

myBooze.getBooze('wine').consumption_style() // this will return "I got class"
