For the barbecue restaurant to charge a gas fee for this practice, my views are as follows:

1. From the point of view of the commercial tenants, this practice is reasonable to a certain extent. The barbecue needs a lot of gas and barbecue grill, which directly increases the cost of merchants. Charging a gas fee can subsidize this cost to a certain extent, which is conducive to the profitability and operation of the merchants.

2. But from the consumer's point of view, the cost of barbecue should be included in the price of the food. Charging extra for gas will increase the travel cost of consumers, and is not consistent with other restaurants' charging methods, which will have a certain impact on the consumer experience, and is not reasonable.

3. If the barbecue restaurant in the pricing has taken into account the cost of gas, then the additional charge is a double charge, which is clearly unreasonable. Therefore, it is necessary to set the price structure of the barbecue restaurant on the reasonable calculation of the cost factors, to avoid repeated consideration of gas costs.

4. There are also some barbecue restaurants to take the way to let customers provide their own fuel, which can reduce the cost of merchants to a certain extent, but also to avoid the problem of double charges to customers. However, this also increases the difficulty of the customer to use, for some customers is not very convenient.

So, overall, there is some controversy over whether barbecue restaurants should charge for gas. This requires a combination of cost-benefit and customer experience. If the cost of fuel has been taken into account in the pricing, the extra charge is obviously not reasonable. But if the cost of fuel is high and difficult to fully balance in the price, take a certain amount of gas charges or let customers bring their own fuel, etc., is also a compromise.

This requires barbecue merchants in the development of prices and marketing strategy, fully estimated the various types of cost components, and take into account the experience of different customers, to provide a reasonable and not lose the preferential program. Let both parties feel fair and satisfied, this is the best business choice. If the price is right and the service is good, most consumers will understand and accept a certain amount of gas costs.
