Your young man really had ants in the cafe, there were no ants in your coffee, you brought them there already with a straw that you mixed up. Latte is the milkiest coffee drink, it contains one serving of espresso with a volume of 30 ml and four servings of milk, there is very little coffee in it. If you wanted a stronger coffee, you should have ordered at least a cappuccino. We have already apologized several times for your young man's coffee, we did not charge you money, although you ordered two lattes and two espressos I'm sure no one would want to be in such a situation, but it happens sometimes, it's an isolated case, and it's already happened. We have apologized and taken action, I do not know what else we could do to improve your mood. I hope that you will come to us again and give us a chance, because we are trying very hard to make all our guests happy
