Well, we used to have a refrigerator in my previous company with a good collection of food items. In fact, whenever we felt demotivated, we would go and pick things from there. It was a simple method that we practiced.
Each one of us would provide a list of items we needed, usually once or twice a month. For example, wafers, Tropicana, Perk (we used to get the big box), etc., and store them in the refrigerator. The amount used to be deducted from our salary based on the individual's list provided to HR. Yes, we only took things we had ordered.
Apart from that, we used to get snacks from our office twice a day along with a tea/coffee break. In the morning, we would have 2 biscuits and coffee. In the evening, we would have tea with snacks that varied every day, such as Kesari, mixture, sandwich, groundnuts, etc. All these snacks were provided by the company.
I would suggest considering the following items:
- Lemon Iced tea powder
- Pringles/Lays
- Wafers/chocolate box
- Corn
- Tropicana/Real/Saint
- Corn puffs
- Biscuits - Good Day/Milk Bikis
- An occasional pani puri
Please let me know if you need any more information or assistance.
