You can still get fresh, hot pacos at the Tavern, and hopefully soon Gallagher's. Quality Meats will have the frozen pacos and cowpies, and you could still pick some up at Paco Packers (right beside the Crystal Pistol) as long as it is within the operating hours of PP.
As to what happened, it was simply a matter of time and money. The manager started out with the best of intentions, staffing it with herself, her daughter and three employees. However, over time, the demand did not support the additional employees, and when you are only making $2.00 per meal, it takes a whole lot of meals just to pay the rent and utilities, let alone additional staff and hope to make any money. The only set-up that the Crystal Pistol could support was the owner and her daughter. This became difficult because on the busy days, two people are not enough to cook, wait tables, answer phones and deliver food. However, there were many slow days which could not justify hiring extra people to just sit around. Since there is no way to gauge what days are going to be busy and what days are going to be slow (and there was absolutely no rhyme or reason), you end up making people mad when it is busy and service is slow. Thought was given to raising prices, but seeing as how there were complaints when prices were raised $0.50 per meal, they knew that was not an option.
Besides, the whole situation proved less than ideal as the owner already has another business and was working from 5:30 a.m. to after 10:00 each night, with no chance to attend any family functions. When a function was important enough to attend, the place had to be shut down, which further angered clientele.
Bottom line, to basically have any sort of life, they decided that it was not worth working 18 hour days to make no money.
When you are out eating at other restaurants, mention that you would like them to carry the products (although this will obviously not work with the corporate chains). Paco Packers would love to sell them to anyone interested.
