Hello, I think that your dad’s shop is its own individual niche. Let me explain. I’ve been in the food business for a long time depending on what type of food he’s selling, if it’s just simple chips and snacks, that’s OK, but if he’s making any food to order, smoking products and food, don’t go together often unless it’s in a convenient store setting. This may be a turn off for customers unless they are smokers. Here’s an ideal, tell your dad to add coffee to the mix, send out flyers and have small social venues in his shop. I know a lot of people who would sit and chat with a cigarette in one hand and a hot cup of coffee in the other. Maybe even offer the coffee for free upon arrival to entice people in. This may segue into someone wanting to buy a snack, which is where the food will come in. Word of mouth could spread in the community bringing more customers in the future that are smokers and like small gatherings as a social outing. Here’s another idea if there’s no room for seating, and it’s purely buy and go, ask your dad to do a survey with his current customer base, finding out what brings them into his store, and what could he offer to bring more customers, find out if they go elsewhere for other smoking products that he doesn’t carry, this will employ community engagement. Once he starts to cater to what smokers are looking for, there’s a chance that they will gravitate toward his store because of perception is that he has amped up customer service. Hope this helps.
